High-Precision Laser Machines for Coins and Currency

ACSYS laser technology is setting new standards in the coin and printing industry, such as through our patented Pulse Forging^® for laser polishing of surfaces without changing tools. This makes us the market leader in laser processing for mint and print. Renowned mints and printers worldwide rely on our unique combination of hardware, software and processes to realize innovative designs with the finest structures or non-copyable security features using laser technology.
3D Laser engraving

Precise 3D laser engraving is particularly suitable for intricate structures and engravings in molds, stamps, or embossing dies. 3D precision engraving with laser technology is particularly advantageous in the field of coin die production. This is particularly economical because several process steps are covered by the laser, such as engraving, frosting, and polishing with the help of ACSYS’ our patented Pulse Forging^® technology.

Our systems can facilitate:

Relief engraving for a stable and precise process that produces reliable and burr-free results

Free-form engraving backed by Z-axis tracking for exact three-dimensional marks

High-relief engraving for deep marks with extensive detail
Relief engraving

Whether extremely fine details with a femtosecond laser or a particularly fast engraving process thanks to a premium performance galvo head: ACSYS offers numerous options for relief engraving directly on hardened steel with Direct Laser Engraving. And all this without tool wear and with a stable and particularly precise process in which the engraving does not damage the surrounding surfaces. Burr-free engravings also make it possible to pre-polish the stamps. Laser engravings can also be applied directly to surfaces with a slight curvature. Take advantage of Direct Laser Engraving to engrave minting dies with Ultra Short Pulse lasers extremely quickly, burr-free and without deflection.

Free-form engraving

Free-form surfaces can be precisely engraved using ACSYS laser technology without any loss of quality. The absence of a 5-axis system ensures that there are no undercuts in the process. Another advantage is the fact that the process direction always corresponds to the demolding direction. Dynamic Focus Control (DFC) and software-controlled Z-axis tracking in the engraving process ensure increased precision. This opens up new design possibilities for three-dimensional coins and spheres with the help of free-form laser engraving.

High-relief engraving

With high relief engraving, it is possible to achieve disproportionately deep engravings with the highest level of detail. The ACSYS software offers special parameters for this and with the Dynamic Focus Control (DFC) extension, frosting effects for high relief engravings can also be realized. Contactless processing means that the laser as a tool cannot wear out or break, which is an additional benefit of laser processing.
Frosting & Surface finishing

Another area of application for the laser is the effective, targeted matting of polished molding tools such as dies for coins or medals. In addition, laser polishing with Pulse Forging^®, patented by ACSYS, offers a further option for reducing the overall process time and increasing cost-effectiveness.

With our laser systems, you can:

Apply different frostings to a single tool or component

Create a perfect imitation of a sandblasted surface

Use pixel graphics to create frosting gradients

Generate a clean, smooth, and shiny surface
Frosting / matting

A perfect imitation of a sandblasted structure can be achieved through the targeted use of lasers. Other effects and structures are also possible by setting the appropriate parameters. ACSYS laser technology can also be used to apply different frostings (multi-frosting) to a single tool. Each stamp is given its own individual frosting, which is generated randomly and is not repeated. Another plus is the quick and easy positioning using the unique LAS HDµ camera system.

Gradient frosting

The frosting wizard in the ACSYS software can be used to create pixel graphics as frosting gradients. The soft transitions of the frosting, which are created by a patented algorithm for randomly arranging the dots, are particularly impressive. The density of the points is adjusted to avoid burns. Gradient Frosting enables a seamless transition between different frostings and different frosting patterns are possible with the various filters of the Frosting Wizard.

Pulse Forging

With ACSYS Femtosecond Lasers and the patented Pulse ^Forging® technology, you can make surfaces clean, smooth and shiny – similar to polishing. Neither the material properties nor the hardness of the treated material are changed. In combination with Direct Laser Engraving, precise engravings with filigree gradients and finely polished surfaces are possible without changing tools. Pulse ^Forging® works more accurately than any other process and smoothes even the smallest structures with a surface roughness of SA 0.1 µm.
Hallmarking

Hallmarking is a marking process in which a precious metal is marked with a series of component markings to protect customers from fraud and to ensure that the precious metal content has been independently verified and confirmed. Our laser systems excel at this application and can enhance your operations.

Repunch / hallmark / stamp mark

For authentication, tracking and increased security, microtexts or security features are either applied directly to a coin using direct laser engraving, or a laser engraving is created on a die. In addition to logos, serial numbers, purity grades and barcodes, other information can also be applied to the material with direct laser marking on precious metals. In addition to flat products, rings and other jewelry can also be processed using this method.

Intaglio engraving

The intaglio technique is mostly used for seal stamps. The surface of a metallic stamp blank is removed layer by layer using laser technology to create an intalgio engraving depth profile on the stamp printing plate.

Intaglio laser engraving

Burr-free intaglio engravings on stainless steel or nickel material can be produced particularly finely and precisely with ACSYS Ultra Short Pulse lasers. Small optics and perfect beam quality enable extremely filigree structures. Microtexts and security features (e.g. rainbow effect) can be incorporated at the same time. Further effects are possible due to different wavelengths of the laser source. The ORCA µ with vibration-reducing granite structure provides the perfect basis for a particularly large working area for printing plates.
Security features

To increase counterfeit protection, non-copyable security features can be created using laser technology. In contrast to conventional printing technology, laser systems from ACSYS only offer individualization and personalization abilities, but they can also process complex geometries and create inlays in deep layers of the material.

Security features include:

Latent and tilt images that change based on the viewing angle

Micro-engraving for marks that can only be read under a magnifying glass

Rainbow and iris effect refractive structures on metallic surfaces

Tilted contour lines in a two-dimensional space that creates a 3D effect
Micro-engraving

Micro features appear like a line to the naked eye and can only be read under a magnifying glass. Laser technology can be used to create corresponding micro-engravings with a depth of less than 80 μm and a size smaller than 60 μm in order to realize microtexts or hidden objects or codes as a security feature. ACSYS laser systems are equipped with a quick changer for interchangeable optics, allowing different security features to be realized, from microtext to latent images (wobble images).

Rainbow effect / Iris effect

ACSYS laser systems with both nanosecond and femtosecond lasers offer innovative solutions for creating refractive structures on metallic surfaces, such as chrome, embossed steel or stainless steel, for individual security features and optical effects. The colors are not applied directly with the laser, but a structure is created that can be applied to the workpiece by embossing, plastic injection molding or laminating.

Tilted contour lines

Shadow vectors, also known as tilted height lines, can be generated with ACSYS laser systems as 2D tool paths using a 3D model. The removal is two-dimensional, but creates a 3D effect. A combination with various laser processes, such as frosting, rainbow effect or micro-engraving, is possible.

Latent image / Tilt image

3D micro-engraving is used to create fine pyramid or cone structures in the material. The different sides of the structures created can be designed differently using laser processing. This creates visual effects that generate between two and four different images depending on the viewing angle. With laser technology, such tilt effects can be realized quickly, efficiently and very delicately. The laser also offers the advantage of being a wear-free and particularly flexible tool. In terms of effectiveness and efficiency, laser systems from ACSYS are a real plus for the production and finishing of embossing stamps and printing plates.
Performance & Sustainability

Making laser processes more efficient and sustainable is deeply rooted in the DNA of ACSYS. With novel technologies such as rapid area scan (RAS) or targeted PVD decoating of embossing dies with femtosecond lasers, ACSYS offers targeted innovations with significant added value for the mint & print industry.

High-Speed & High-Quality Digitization

With the unique Rapid Area Scan (RAS) process, you can speed up the high-precision digitization of templates for the creation of 3D models by up to 30 times – including the transfer of data to CarveCo. Instead of a single measuring point, a complete measuring line is projected. This means that an original can be scanned in blocks and significant time savings can be realized during the scanning process. The scanned segments are merged by the software without any loss of quality. The line width can also be adjusted flexibly and easily. And with the precise preview of the scan, you have full control.

Laser PVD decoating

The residue-free removal of PVD coatings (CrAIN, TiN) on embossing dies using laser technology from ACSYS contributes to improved sustainability and longer tool life. With the help of ultra-short laser pulses, only the protective PVD layer is completely removed, but the underlying relief is not damaged. And our patented pulse forging process subsequently ensures that the surface of the minting die can also be partially polished. And the best thing is that this process can be repeated without any noticeable loss of quality.

Laser Roughing & Finishing

Engraving in record time and with constant precision ACSYS takes the classic processing strategies of scrubbing and finishing to a new level: The intelligent software from ACSYS makes it possible to divide complex objects into zones. These individual parameters are precisely matched to the surface requirements and the desired level of detail and are optimally engraved using the latest laser technology. The new ultra-fast engraving setup achieves the highest removal rate compared to the current femto parameters, with constant precision and without any hardware changes. At the same time, Performance Toolpathing ensures optimum laser paths and cleaning and smoothing intervals that reliably prevent the photocopying effect. The result: up to ten times faster than CNC or nano laser engraving – with the highest quality and maximum efficiency.

Watches & Jewelry

Filigree components require maximum precision for production and finishing at the highest level. This is why ACSYS is the first port of call for high-quality laser processing systems in the watch and jewelry sector.

In particular, the precise engraving, structuring, fine cutting and fine welding of precious metals can be produced and finished on laser systems specially tailored to the needs of the watch and jewelry industry. Innovative solutions, such as laser polishing via Pulse Forging^® without changing tools, are the result of our many years of expertise in working with materials, systems, and lasers for watches and jewelry.

Precision mechanics

Laser technology plays a decisive role in the manufacture of mechanical watches. Whether laser fine cutting of the finest components, such as gear wheels, hands, or dials, or laser fine welding or micro-welding of the balance wheel or decorative elements – the precision and efficiency of ACSYS laser systems provide the perfect basis for the highest quality requirements combined with cost-effectiveness.

Fine blanking of gears

Ultra Short Pulse lasers in particular can be used to cut free-form geometries from temperature-sensitive materials precisely and with maximum edge quality. The material is not melted or thermally stressed due to the low energy input, which means that precise cutting edges for filigree structures can be realized.

Micro welding

In the watch and jewelry sector, micro-welding with laser technology sets standards in precision manufacturing. With laser systems from ACSYS for fine welding, tiny metal components such as those found in watch movements or filigree jewelry can be joined permanently and gently. Micro-welding ensures high joint strength with minimal thermal influence. Especially with precious metals such as gold or platinum, micro welding enables seamless and aesthetically pleasing results without affecting the material structure.

Fine engraving

Precise laser fine engraving enables particularly intricate structures and designs to be incorporated into jewelry, watches, or lifestyle products in the watches and jewelry sector. With the help of ACSYS laser systems, even complex 3D engravings can be realized without the need for any attachments.

Gold, silver and other high-quality precious metals in particular can be processed precisely and economically. Whether used for security features, hallmarks, or individual engravings, laser systems from ACSYS remain flexible, letting you combine the engraving process with other process steps, such as frosting or laser polishing, in one system.

Engraving watch backs

Watch backs can be finished with numerous engraving effects and structures, depending on the parameterization and the type of laser. It is also possible to create different frostings (multi-frosting) with ACSYS laser systems. It is also possible to individualize and mark components with personalized data. The same applies to the generation of security features and consecutive numbering or labeling.

Circumferential, seamless laser engraving on rings

With NC-controlled dividing heads and the high-precision Live Adjustment System (LAS) from ACSYS, which displays a camera-supported live view of the result on the screen, maximum accuracy and repeatability can be combined at high traversing speeds. In particular, the perfect coordination of hardware and software, as well as process-related parameters, ensures that laser engraving is applied around the circumference of rings without leaving any marks.

Internal labeling & engraving of cambered rings

The internal inscription of cambered rings is one of the supreme disciplines of jewelry finishing, as is the seamless, all-round laser engraving and inscription on the circumference of rings. Thanks to the perfect combination of laser technology, software and process expertise, laser systems from ACYS are perfectly suited for the internal marking of rings. The result is maximum precision with maximum flexibility for the highest quality requirements with valuable materials.

Surface finishing

Laser systems in the watch and jewelry sector are used for the effective and efficient matting of watch backs, as well as for laser polishing or the creation of jewelry colors on metallic surfaces. The combination of these processes allows companies to achieve superior finishes without the typical abrasion that is associated with traditional mechanical processing. Additionally, a machine that can produce color expands the design possibilities to attract new consumers who want a unique product. By combining several process steps in one tool, ACSYS laser systems enable you to reduce the overall process time and increase efficiency.

Spot colors / rainbow effect

ACSYS laser systems with both nanosecond and femtosecond lasers offer innovative solutions for creating refractive structures on metallic surfaces, such as chrome, embossed steel or stainless steel, for individual security features and optical effects. The colors are not applied directly with the laser, but a structure is created that can be applied to the workpiece by embossing, plastic injection molding or laminating.

A perfect imitation of a sandblasted structure can be achieved through the targeted use of lasers. Other effects and structures are also possible by setting the appropriate parameters. ACSYS laser technology can also be used to apply different frostings (multi-frosting) to a single tool. Each stamp is given its own individual frosting, which is generated randomly and is not repeated. Another plus is the quick and easy positioning using the unique LAS HDµ camera system.

Sapphire crystal & ceramic

Ultra-short pulse lasers (USPL/UKP) can be used to process particularly hard and transparent materials. Especially in the watch industry, ceramic is used as a material for bezels and other components. Ceramic components can be processed with high precision using ACSYS femtosecond lasers. Lasers with ultra-short pulses are also used for cutting and drilling sapphire watch crystals. This extremely hard material can hardly be processed using conventional methods – laser systems from ACSYS offer a real alternative here.

About Femtosecond Lasers

ACSYS employs advanced femtosecond laser technology, capable of removing less than 1 µm of material with each pulse. Pulse durations ranging from picoseconds to femtoseconds on our ultra-short pulse lasers allow unprecedented control over the energy transferred to the material. This enables highly precise engravings with extremely fine depth resolution without significant thermal damage.

Micro-engraving with these lasers is ideal for producing embossing stamps, authenticity seals, and detailed marking applications. Open up a new world of precision processing with our USPL/UKP systems today.

Cutting sapphire crystal / watch glass

With the help of ultra-short laser pulses and the associated high intensity peaks, extremely high cutting quality can be achieved when cutting extremely hard materials. The combination of laser beam source, special software parameterization and coordinated optics ensures an optimally shaped laser beam for cutting sapphire glass. This process can be used in the watch industry as well as for cutting LED glass wafers in the electronics sector.

Texture ceramic bezel

Ceramic inlays are considered the ultimate in watches. With a Vickers hardness of 1250 HV, a ceramic bezel is not only resistant to heat and corrosion, but is also a real haptic highlight. This also applies to the design, as selective laser ablation is used to remove the thinnest layers of ceramic in order to create three-dimensional recesses – for example for multi-colored scales. ACSYS laser systems allow the creation of intricate structures, precise markings and the targeted processing of ceramic surfaces in the μm range.

Machine & tool construction

High-Precision Laser Machines for Machining
and Tooling

Laser processing systems from ACSYS perform important tasks in machine and tool construction. The spectrum includes laser integration in machines and systems, versatile laser applications for the manufacture of tools, and the cleaning, repair and functionalization of materials. Leading manufacturers in machine and tool construction rely on the unique combination of laser technology, software, and process know-how from ACSYS for efficient and precise laser marking, laser engraving, laser structuring, laser cutting and laser welding.
Automation

Process automation is playing an increasingly important role, especially in machine and tool construction. That is why we offer laser processing solutions tailored to your needs and individual challenges from a single source. Anyone can promise you this, but we have proven it in practice in numerous projects – it is not for nothing that market and quality-leading companies have been relying on ACSYS solutions for more than 20 years.

Our systems can help with mechanical automation, such as rotary tables, conveyor belts, or film handling with rollers for winding and unwinding, optical solutions and special solutions, such as wafer handling or the separation of bulk goods, and software solutions with automatic pallet recognition via RFID and corresponding parameterization of the system. Using effective laser systems in these processes allows you to benefit from:

High precision and repeat accuracy

Optimized operations that cut down on time and resources

Reduced costs

Maximized efficiency for production
Material feeding & handling

Whether fully or semi-automated – efficient and safe material handling is simply part of modern production. The spectrum ranges from material feeders to palletizers, tray feeders, vibratory or step conveyors, reel-to-reel or coil feeders, automated guided vehicles (AGVs) and, of course, robots. The latter can be used not only for material feeding, but also for laser processing. Ask about our customized automation solutions for machine and tool construction.

Conveyor systems into the machine

One of the most common automation solutions in the field of laser processing are product carriers. In combination with other handling solutions or conveyor systems, such as conveyor belts or shuttles, workpieces can be processed and picked with high precision and repeat accuracy. Standardized solutions help to optimize processes and thus save time, money and resources. This ensures maximum efficiency in machine and tool construction.
Spot and Seam welding

Metals and plastics can be joined particularly finely, precisely, and permanently with ACSYS laser systems. Laser welding is carried out without the addition of material, which means that the processed materials retain their original properties. And with the flexible power and pulse design, special effects as well as special pulse shapes and trains can also be created.

Wheter for the smallest spots or meter-long weld seams, ACSYS laser welding systems for tool, machine, and mold making deliver:

High-quality, precise, and efficient welds

Increased weld and part stability

Repeat accuracy, facilitating streamlined production

Reliable operator control

Both metal and plastic welding capabilities
Metal welding

The precise and efficient welding of assemblies and workpieces with laser technology in machine and tool construction leads to increased stability and safety. ACSYS laser systems ensure strength and durability in laser welding and make a decisive contribution to quality and performance in production technology through robust and reliable metal connections.

Plastic welding

A typical application example is the laser welding of complex plastic components that require high strength and an exact fit, such as when joining protective housings and insulating components. Laser welding systems from ACSYS are also used to join plastic housings in electronic control units, where the tightness and durability of the weld seam is crucial. Laser welding enables clean, controlled and efficient processing and is therefore crucial for quality assurance in the production of plastic components.
Permanent Markings

Laser marking ensures that important information is permanently applied to tools, molds and machines. Particularly in tool and mold making, where rough conditions prevail due to corrosion, abrasion or dirt, marking with laser technology offers significant advantages over conventional methods. In addition, ACSYS laser systems offer the option to feed barcodes, serial numbers and logos into the software.

Benefit from a wide range of different laser systems, automation and processes to achieve high-quality, permanent markings and engravings – even in series production with high throughput.

There are numerous subsets of laser marking that ACSYS systems excel at, with some options including:
Laser engraving

Tools and machine parts can be laser engraved with identification numbers, technical specifications or manufacturer information. Laser engraving is characterized by precision, durability and resistance to wear and corrosion. Especially for high-quality components, engraving with ACSYS laser systems with software-controlled insertion of data matrix codes and individual serial numbers offers the possibility of ensuring permanent marking for traceability and quality control.

Black Marking

Ultra Short Pulse Lasers (USPL) from ACSYS can be used to create long-lasting, corrosion-free and viewing angle-stable markings on aluminum, stainless steel or other metallic or chrome-plated surfaces in the form of black markings. Whether it’s serial numbers, data matrix codes, lettering or extremely intricate graphics: Black Marking ensures abrasion-resistant marking.

White marking

The white marking is the slight melting of the surface, so that small melt craters are created, which then diffusely reflect the light, similar to a sandblasted surface. Only the tiniest amount of material is removed. The removal rate for white marking is significantly less than 1µm. In principle, white lettering is a special form or borderline form of engraved lettering. Engraving lettering generally aims to achieve a dark discoloration of the engraving base, while white lettering aims to achieve a light surface.

3D laser marking

The lasered scaling with “twist” on a turned step drill (e.g. made of burnished HSS) demands a lot from a laser system. Turned scaling on the step drill requires an NC-controlled dividing head and powerful software. All in all, a perfect application for an ACSYS laser system. The step drill is simultaneously rotated during laser processing to ensure the exact position of the numbers.
Laser Cutting

Laser technology can be used to cut metals and plastics, or, more precisely, to thermally separate them. ACSYS laser systems really come into their own when performing the precise cutting of flat materials with high edge quality. Our laser systems are also capable of high-precision and fast interpolated laser cutting. There are generally three laser cutting processes. These differ in the additional gas that is introduced into the parting line axially to the focused laser beam. And fine cutting with ultra short pulse laser (USPL) takes precision, edge radius, and quality to a whole new level.

Fine blanking

Laser fineblanking is ideal for the production of complex tools and shapes. For example, ACSYS laser systems can be used to produce fine saw blades or complex punching tools with extreme precision. Hard metals or high-strength steel can also be processed precisely and efficiently using laser technology. Laser systems from ACSYS impress with their flexibility in terms of the materials to be processed and the possible processes and designs, as well as with regard to automation and integration.

Separating printed circuit boards

Cutting printed circuit boards (PCBs) with laser technology is an advanced method that offers numerous advantages. In particular, the high precision, even with complex cutting patterns, the contactless processing and the fast and efficient process should be mentioned here. PCBs can be produced with ACSYS laser systems even for prototypes or small series – you always have the process in view with the Live Adjustment System (LAS). And the adaptability for different materials (FR4, CEM, ceramic, flexible PCBs) as well as the simple adjustment to different board thicknesses make laser cutting of PCBs the preferred method in modern electronics production.
Miro Engraving and Surface Functionalization

Self-cleaning, antibacterial, or non-icing surfaces are just a few examples of laser-based surface functionalization. The latest findings from bionics are used, such as via direct laser interference patterning (DLIP) to improve the adhesion of coatings, increase the corrosion resistance of materials, or minimize friction. ACSYS ultra short pulse lasers (USPL) help you to increase the service life of tools, improve precision and efficiency in production, and establish sustainable alternatives to conventional processes.

Our laser systems are adept at:

Creating precise chip grooves that diamond grinding simple can’t match

Producing wear-free and reliable results

Facilitating laser texturing for improved friction and better wear resistance

Using DLIP methods to improve adhesion or create liquid-repellent surfaces
Laser micro-engraving 3D chip groove

Polycrystalline diamond cutting edges (PCD cutting edges) are very difficult to machine due to their inherent hardness. Spark erosion or grinding with diamond grinding wheels are only suitable for sharpening. However, if precise chip grooves for controlled chip breaking and high surface quality are to be introduced into the material, laser machining is the only solution. This is because PCD is the hardest cutting material of all, with a Vickers hardness of 6500 HV compared to around 1800 HV for carbide. With the help of laser micro-engraving, 3D geometries in PCD can be realized wear-free and with high precision.

Laser texturing

In functional terms, laser texturing helps to improve friction properties and increases the wear resistance of components. From an aesthetic and design point of view, the texturing of surfaces enables the creation of graphic details, for example the laser texturing of injection molds. ACSYS laser systems, combined with our many years of expertise, impress with their ability to process a wide range of materials. Customized surface textures are increasingly used in specialized applications, especially in tool manufacturing, to improve performance and tool life.

Direct Laser Interference Patterning (DLIP)

DLIP uses the interference of two or more laser beams to create precise patterns on the surface of a material. These patterns are created by superimposing the laser beams, creating areas of high and low intensity. In this way, the surface properties of tools can be improved or specific surface structures can be created that improve adhesion or are liquid-repellent, for example. With their unique combination of hardware, software and processes, laser systems from ACSYS enable optimum integration of DLIP technology.

Precise Laser Machines for Medical Devices and Equipment

systems from ACSYS ensure maximum precision, flexibility, and sterility for medical products. Even the smallest components can be efficiently and precisely marked, engraved, structured, cut, and welded using laser technology, and our systems are designed to facilitate all of these applications for our clients.

Manufacturers of medical technology products have been using our customized laser systems for the production of surgical instruments, implants, and medical devices for many years. Due to our years of expertise in providing laser systems for medical technology, we are the first port of call when it comes to top-quality, maximum process reliability and compliance with medical and hygiene standards in the manufacture of medical products and solutions.
Permanent marking

With the help of laser marking, important information can be permanently applied to implants, medical equipment and MedTech devices. Especially when it comes to cleaning and sterilization, marking with laser technology offers an advantage over conventional methods. In addition, individualization via barcodes, logos, or serial numbers can be easily integrated into the software. Even complex 3D geometries can be marked to a high standard using laser marking.

The medical field also faces UDI requirements, with UDI standing for “unique device identifier.” These identifiers need to be present on many types of equipment, as well as packaging and labels, to indicate exactly what a product or a component is. Elements that may be featured include a Global Trade Item Number, date codes, batch numbers, serial numbers, expiration dates, and more.

Laser marking and laser engraving are ideally suited for adding UDI information to medical equipment, as the processes are fast, precise, repeatable, and, as mentioned above, sterile.

Specific applications of marking and engraving for medical purposes include:

Black marking, creating permanent marks via short-pulse lasers, avoiding the need for corrosive chemicals

UV plastic marking ideal for many medical devices, from catheters to insulin pumps and beyond

Ceramic labeling to avoid damaging the material, as is common in other methods

Depth scaling, also called annealing, which is suitable for dental marking and other needs

View our slideshow below for a more in-depth look at these processes.
Black Marking

Individualized medical devices, such as artificial joints, are marked in accordance with UDI using laser technology. With black marking, the laser marking on the implant is permanent, high-contrast and corrosion-resistant. In addition, surface functionalization with the aid of ultra-short pulse lasers (USPL) offers new possibilities for supporting the growth of implants through microstructures on the surface without having to resort to corrosive chemicals.

UV plastic marking

With a UV laser source and the right combination of optics, software and process parameters, extremely fine markings with high contrast can be created on silicones and white polyamides. In medical technology, the process is particularly suitable for UDI marking of catheters, insulin pumps and instruments in accordance with FDA and MDR traceability requirements. In ACSYS laser systems, UV lasers are mainly used for marking plastics in the MedTech sector due to their short wavelength and the correspondingly low heat input during marking.

Labeling of technical ceramics

In the medical sector, materials and components are subjected to frequent cleaning. High temperatures, aggressive chemicals or ultrasonic baths are often used to achieve sterility. There are very high requirements for the markings, scaling and labeling on the individual components. Laser marking and engraving offers the enormous advantage over conventional methods in that no application takes place and the material is not attacked or becomes brittle.

Depth scaling

Annealing marking is the ideal marking process for the dental industry. The precise depth scales in the millimeter range are absolutely abrasion-resistant and do not attack the material of the drill bit. The material is heated in a targeted manner to influence its color properties. In addition, the color of the scaling can be changed through targeted parameterization of the laser in order to achieve even better readability of the depth scale.
Fineblanking

Laser fineblanking is particularly suitable for medical products that are based on tubular blanks. It can be used to cut a wide range of extremely fine components out of metal, plastic, or organic material without contact, with applications ranging from stents to aortic valve replacement (TAVI) and more. In addition, ultra short pulse lasers (USPL/UKP) offer an efficient and precise solution for fine cutting of temperature-sensitive materials such as nitinol.

Both tubular laser cutting and foil laser cutting approaches are possible, with benefits including:

High-precision results

Burr-free and clean cuts that help maintain tight tolerances

Gentle processing of sensitive materials

Production of complex patterns, fine contours, and tight radii cuts

No material deformation
Tubular laser cutting

Laser fineblanking offers high precision and efficiency for cutting tubes and tubular parts in medical technology. When cutting metal stents, lasers enable a precise, burr-free cut, which is crucial for maintaining tight tolerances. Polymer stents and cannulas can be fine-cut cleanly and precisely without contact using ACSYS laser systems. Laser cutting allows sensitive materials (e.g. special metals such as titanium or platinum) to be processed efficiently and gently.

Foil cutting

Complex patterns, fine contours and tight radii can be realized with ACSYS laser cutting systems, even on the thinnest films, without stressing the material. Non-contact processing prevents material deformation and ensures precise cuts. This property is particularly advantageous for thin, sensitive film materials. Laser cutting enables fast, efficient and precise processing, making it ideal for applications in medical technology.
Micromachining

The possible applications for laser micromachining, or microstructuring, in medical technology range from osseointegration and microfluidics to the lotus effect. Femtosecond lasers can be used to create micro- and nanoscale structures on almost any surface and geometry.

conventional processes such as etching technology, processing with ultra-short pulse lasers (USPL/UKP) offers significant advantages in terms of quality, efficiency, and environmental friendliness. Femtosecond lasers can also be used to clean surfaces, for example to remove impurities from upstream processes.

Benefits of this subset of laser processing include:

Working with sensitive materials like ceramics, glass, and plastic

Creating antibacterial and nonstick surfaces

Sterilizing surfaces via laser cleaning to meet the needs of the medical field

Creating microscopic holes via laser drilling for diverse purposes

Creating precise patterns on surfaces via direct laser interference patterning
Microstructuring

ACSYS Ultra Short Pulse Lasers (USPL) can be used to create micro- and nanoscale structures on almost any surface. Even sensitive materials such as plastic, glass, ceramics or semiconductors can be functionalized with laser textures. For example, implants fuse faster with the tissue if the material surfaces are roughened in a targeted manner. And the same technology is suitable for creating antibacterial and non-stick surfaces – inspired by microscopic patterns found in nature.

Laser cleaning

Medical devices, surgical instruments and implants can be cleaned and sterilized using laser technology. Laser cleaning with ACSYS laser systems effectively removes biofilm, deposits and contamination from medical instruments and implants, dental tools and endoscopes. Completely without aggressive chemicals or cleaning agents and therefore particularly sustainable, without compromising on maximum sterility and cleanliness.

Laser drilling

Laser drilling is a key technology in medical technology, which is essential for the production of complex microstructures. For example, it enables microscopically small holes to be drilled in medical stents, allowing precise drug delivery. It is also used in the production of micro-vias on printed circuit boards for medical devices to ensure high-precision electrical connections. ACSYS Femtosecond Lasers offer accuracy and efficiency for numerous medical applications.

Direct Laser Interference Patterning (DLIP)

With the help of DLIP technology, interference patterns are created using two or more laser beams to generate precise patterns on the surface of a material. For example, by applying functional laser structures to medical implants, sandblasting effects can be achieved that offer significant improvements over traditional methods in terms of both cell adhesion and cell proliferation. With their unique combination of hardware, software and processes, laser systems from ACSYS enable optimum integration of DLIP technology.

Interiors

Positive user experiences are at the heart of the development of new interior designs in the automotive sector. A trend toward new materials, adaptive lighting, and dynamic design has developed, particularly as a result of electromobility and electric vehicles. Discover how you can use ACSYS laser systems to achieve high-quality solutions when designing interior elements, while reducing time and costs:

Say goodbye to complex etching processes for graining and perforation by streamlining everything with laser engraving. The engraving process is perfect for small components and intricate details, and is often faster, easier, and cheaper.

Effortlessly create day/night designs for interior components through laser ablation, removing paint, chrome, foiling, and other top layers.

Forego the expense and hassle of glue, screws, and staples by using high-tech laser welding for key interior parts.
Graining & perforation

The graining of interior trim in the automotive industry is usually etched. A more sustainable processing method is to engrave the surface using a laser to create the corresponding graining. Laser engraving is often simpler and more economical, especially for small parts and complex shapes, such as those found in interior trim in the automotive industry. In addition, defective surface structures in a workpiece can be optically repaired with the laser.

In addition, the creation of high-quality and complex perforation patterns on various organic and textile materials is easier, cheaper and more efficient with the help of laser technology.

Day/night design

The base material can be exposed by selectively removing a top layer, such as anodizing, foiling, paint or chrome. Backlighting can then be used to create day/night designs on switches and other decorative elements in the vehicle interior. There are virtually no limits to the design possibilities with laser ablation, and with the help of the unique Large Field Removal technology from ACSYS, even large 3D workpieces can be provided with the finest structures and patterns without any problems.

Plastic welding

Plastic laser welding of speedometer bezels no longer requires screws, staples or glue. ACSYS fiber laser technology works with a large focal depth, so that process-tolerant welding is possible even if the materials have different wall thicknesses or are not perfectly perpendicular during the welding process.
Exteriors

High design standards, lightweight construction, and cost pressure are the drivers of innovation in the automotive industry. Suppliers of front and rear lights, front grilles, or interior and exterior foiling are just as affected by these factors as car manufacturers themselves. The use of laser technology can reduce component costs and assembly times while at the same time increasing quality and visual appeal. Consider the following options:

Selectively remove paint and coatings via Large Field Removal to create new design possibilities during R&D and production phases.

Avoid the unreliability and unpredictable results of brushing and pad printing, using micro-precise paint stripping for first-rate quality and durability. Add letters, logos, and patterns with ease.
Large-area paint removal

The ^LFR® technology from ACSYS enables the laser processing of 3D components with an area of up to 1,250 mm × 1,250 mm. The entire area can be processed during Large Field Removal without axis movement and the spot size of the laser remains precise thanks to continuous laser processing. This means that visible lugs or overlaps during processing are a thing of the past.

Selective material removal

Automotive rims must meet the highest aesthetic standards and constantly break new ground in terms of design, including individualization. The ultimate here is paint removal with ACSYS laser engraving. Compared to conventional processes such as brushing or pad printing, partial, micro-precise paint stripping with laser technology offers unrivaled quality and durability. Individual lettering, logos and patterns can be realized with the innovative process and create space for new design possibilities.
Electromobility & Batteries

High-performance battery cells are a basic prerequisite for the successful establishment of electromobility and for energy transition as a whole. Efficiency and performance are important components, but so is consistent lightweight construction with innovative compound materials. Your automotive operations can greatly benefit from:

Using laser joining to combine battery components and cells into convenient modules and packs, resulting in higher quality, lower cost, and greater flexibility

Combining alloys, composites, and other battery materials via laser welding, increasing production flexibility, improving quality, and garnering precise, repeatable results

Precisely cutting and shaping battery components and other parts via efficient laser cutting methods, preventing damage to sensitive components
Laser joining

Laser joining plays a particularly important role in battery production. This laser process offers significant advantages over conventional processes in terms of quality, cost and flexibility. This means that individual components or cells can be assembled into modules or packs more efficiently and with higher quality using laser technology. Especially when new multifunctional materials are used, which can often only be processed with a laser.

Laser welding

Whether aluminum alloys for lightweight components, nickel-based alloys or complex composite materials: Battery packs for electric vehicles use numerous different components and materials that have to be welded using laser technology. With ACSYS laser systems, you have maximum flexibility in the choice of materials and achieve the highest quality and repeat accuracy in laser welding.

Laser cutting

Consistent lightweight construction in the mobility sector means that thin sheet metal is increasingly being used. With high-precision fiber laser systems from ACSYS, thin and electrical sheets with a low carbon content as well as copper and aluminum sheets can be cut precisely and cleanly. Low-distortion and low-stress cutting with laser technology ensures perfect cutting edges at high cutting speeds – even with particularly thin and sensitive materials such as those used in the sensor sector.
