At AMB, LANG GmbH & Co. KG will present the Pulsaris 300fs, a solution for highly precise 3D laser machining of tools, molds, and functional surfaces. Femtosecond laser technology opens new possibilities for manufacturing complex structures, ultra-fine engravings, and sophisticated surface geometries—particularly in applications where conventional processes such as etching, EDM, or manual finishing reach their limits.

Thanks to ultrashort-pulse processing, a wide range of materials—from hardened steels and carbides to ceramics—can be machined with high precision and reproducibility. Sharp edges, defined microstructures, and high-quality surface finishes are achieved without tool wear and with a high level of process reliability.

Especially in tool and mold making, this technology offers new degrees of freedom in the design of functional surfaces. Microstructures for selectively influencing haptics properties, visual appearance, or demolding behavior can be integrated directly into the tool surface. Decorative textures, customized surface patterns, embossing structures, and highly precise engravings can be digitally created and reproduced with consistent quality—even in areas that are otherwise extremely difficult to access.

From Data Preparation to the Finished Tool
A key feature of the Pulsaris solution is the combination of powerful laser technology, intelligent software, and many years of process expertise. The process chain developed by LANG guides users from CAD geometry to the finished component. Machining strategies for material ablation, structuring, and surface finishing can be flexibly combined and adapted to specific application requirements.

Automated parameter determination, comprehensive material and parameter libraries, and proven machining strategies support fast and reliable process development. As a result, even highly complex surface structures can be reproduced consistently on individual components, prototypes, or production tooling.

The focus of LANG’s trade fair presentation is therefore not only on laser technology itself, but on the industrial implementation of complete machining processes. Through practical application examples, visitors will learn how digital geometry data can be efficiently transformed into functional surfaces, embossing structures, and highly precise tool contours.

Visitors can meet LANG in Hall 5, Booth 5A33.

Showpiece for the Opening of the New Flagship Store in Prague

Hüttenberg, Germany, June xx, 2026 – To mark the opening of its new flagship store in Prague, BESSERGOLD Mint s.r.o. has produced Europe’s largest silver medal. The showpiece is made of 60 kilograms of 925 sterling silver and measures 73 centimeters in diameter. Since conventional striking was not possible at these dimensions, the models for the obverse and reverse were produced on an Impala 900S from LANG GmbH & Co. KG. They subsequently served as the basis for the medal’s casting molds. For its ongoing coin and medal production, BESSERGOLD Mint also uses an Impala 400express and LANG’s LDIGIT express digitizing system.

The new flag ship store in Prague brings together precious-metal trading, discreet precious-metal buying services, recycling, and products from BESSERGOLD Mint under one roof for the first time. In addition to investment products, the product range includes limited-edition collectibles, exclusive numismatic issues, rare collector coins, and high-quality gold jewelry. The world’s largest silver medal serves as the central exhibit in the new store. It was created specifically for the opening.

The design on this large-format medal shows the first steam locomotive, which was designed and built over 100 years ago in Pilsen, Czech Republic. It pays tribute to the generations of design engineers, locomotive engineers, firemen, and shop workers who shaped the development of the steam locomotive. The design is also available as a collector coin in the store. “With this large-scale medal, we wanted to create an exhibit for the opening of our new flagship store that would immediately impress visitors while also showcasing the craftsmanship of our medallic artists,” says Ladislav Kareš, Sales Manager at BESSERGOLD Trading s.r.o. “Its exceptional dimensions presented us with new challenges. This made the precise production of the models as the basis for the subsequent casting process even more important.”

Striking Not Possible – Milled Models as the Basis for Casting
With a diameter of over 70 centimeters and a weight of 60 kilograms, the medal could no longer be produced using a conventional striking process. Instead, two high-precision models were first manufactured from rigid plastic—one for the obverse and one for the reverse. The milling work on the Impala 900S took around 20 hours in total. A special sand-molding process was then used to create the casting molds for the silver medal from these models.

The Impala 900S CNC milling and engraving machine was used for this project. With its generously sized work area, it is particularly well suited for the precise machining of large-format workpieces and reliefs. The machine’s rigid construction and highly dynamic axis drives create the conditions required for precise positioning and repeatable results.

“The dimensions of the medal required a completely different manufacturing approach than the one used for traditional coin and medal projects,” says Thomas Kozian, Managing Director of LANG GmbH & Co. KG. “The key requirement was the ability to produce the large-format models with a high degree of precision. The Impala 900S provides exactly the capabilities needed for this.”

Impala 400express and LDIGIT express in Daily Production
In addition to this special project, BESSERGOLD Mint also uses LANG technology in its ongoing coin and medal production. The Impala 400express handles milling and engraving tasks in production. The CNC milling and engraving machine is designed, among other things, for the production of embossing dies and tools, injection molds, molettes, and smaller embossing cylinders. It combines a compact machine design with short machining times and high process reliability.

It is complemented by the LDIGIT express digitizing system. This system enables fast, precise digitization of reliefs, free-form surfaces, and models. The captured data can then be used directly for further processing on LANG milling or laser systems.

“In addition to special projects like this, we use LANG technology every day in our coin and medal production,” says Kareš. “The Impala 400express and LDIGIT express help us produce high-quality reliefs efficiently and with repeatable quality.”

As a system supplier with over 35 years of experience in the coin industry, LANG supplies its customers specially developed machines, corresponding software, training, services and control systems from a single source. The product range goes from digitizing system to CNC milling and engraving machines to laser engraving systems. Many well-known mints trust in this LANG package, which offers advantages
in terms of compliance with safety standards, process optimization and economic efficiency. “One Concept - One Partner” enables more effective processes, faster commissioning and shorter production times.

Of course, Lang will also be presenting a new development at WMF this year: The successful Pulsaris 300 model can now also be used with a femtosecond laser. This equipment opens completely new possibilities concerning the 3D processing of minting dies. The precision that can be achieved with the femtosecond laser cannot be compared with the conventional nanosecond or picosecond laser. Compared
to the nanosecond laser's pulse duration of 1 ns, the femtosecond laser emits a pulse every 0.000001 ns. This drastically reduces the wave bandwidth and vaporizes the material almost without heat input. It reduces the thermal effect and ensures smooth, more detailed engravings. This technology shows its strengths in the coin industry in particular: burr-free removal, micro-polishing of the smallest structural
details to create almost reflective surfaces and surprising light refraction effects. All this with a reduced production time of up to 80 %. Besides being aesthetically pleasing, it can be used for completely new security features. Microminting - the smallest structures that are not visible to the human eye - reach a whole new level with the femtosecond laser.

The new femtosecond laser takes coin production into a new dimension in which designers can play with completely new technical possibilities. Visit LANG at booth C10 and let us advise you!

"The new generation of axis systems from our company comes - unlike many other manufacturers - from the development of our mechanical engineering and is accordingly robust and resilient, but still highly precise," explains Ralf Rink, Head of Automation Systems Development at Lang GmbH & Co. KG. The system is versatile and combinable. It can be controlled in stepper motor mode, as well as in regulated stepper motor and servo operation. Optionally, length measuring systems and motor encoders can be used.

As a modular system, LMOVE 300 can be individually adapted. It is designed to work with the controllers of the Express family from Lang and, in combination, enables a flexibly deployable, synchronous point-to-point positioning system. The manufacturer has integrated various functions. The linear axes can be used either as a single axis or combined as a cross table. The connector output is executed either laterally or in the axis direction.

The linear axes are suitable, for example, for handling, testing, and plant systems, mechanical and plant engineering, microscopy, laboratory automation, microassembly, and medical technology. Image processing, wafer inspection, and handling systems are also among the possible application areas.

Hungarian manufacturer of commemorative coins uses the Pulsaris 300 transfers precise raster images for minting coins using the frosting function

Hüttenberg, xx. February 2024 - The production of a coin with a raster image requires special techniques and processes in order to mint the desired motif with precise details and nuances. For the production of its 200 Forint commemorative circulation coins, the mint "Magyar Pénzverő" (Hungarian Mint) therefore relies on special CNC milling and laser engraving machines from LANG GmbH & Co. KG (www.lang.de). The Pulsaris 300, for example, offers functions such as frosting. This allows different shades to be created on the embossing dies - for example for facial structures - and images to be transferred in great detail.

The Hungarian Mint is a state mint that produces circulation coins for Hungary. It is fully owned by the Magyar Nemzeti Bank, central bank of Hungary and is solely responsible for minting coins of the Hungarian forint. In addition to minting circulation coins for domestic use, it also produces a range of commemorative coins, collector coins and medals. The origins of the mint reach back to the founding of the Kingdom of Hungary, when silver denars under the state founder King Stephen I's reign were minted.

Grid image is transferred with the highest precision during minting
When minting the 200 Forint commemorative circulation coin "Petöfi", for example, special CNC milling and laser engraving machines are required to precisely transfer a raster image onto the coin. The coin shows the image of the Hungarian poet and national hero Sandor Petöfi, whose 200th anniversary of birth the coin is dedicated to. With the LANG machines, the Hungarian Mint achieves an even better surface quality in the production of the dies.

Joachim Steidel, Sales Manager of LANG GmbH & CO. KG, explains: "The Hungarian Mint has been relying on LANG's software solutions and special machines for years to produce the dies for its coins. Our Pulsaris 300 was used for the first time in 2015, followed by the Impala 400express in 2017. With the help of the Pulsaris 300, important functions such as frosting can be used. This is particularly important for minting a coin with a face contour, as many shades are used here. This cannot be achieved using simple linear structures."

The Pulsaris 300 laser engraving machine is used to produce and finish high-quality embossing dies with the finest structures. In addition, surface processing with rainbow effects can be realized in just a few seconds. This opens up a wide range of possibilities not only for the coin industry.

The Impala 400express milling machine is also specially designed to fulfill the requirements of the coin industry. The machine is equipped with modern drive and control technology and guarantees continuous high-speed machining.

As a system supplier with over 35 years of experience in the coin industry, LANG offers its customers specially developed machines, corresponding software, training, services and control systems from a single source. The machines and systems for lasering and engraving are all-in-one solutions, not just for the coin industry.
