We are deeply saddened to say goodbye to our senior partner and managing  partner

Volker Kozian

* June 13th, 1951

who passed away on March 28, 2025 after a serious illness.

A large part of his life was characterized by his work - with foresight and tireless commitment, he managed LANG GmbH & Co. KG since 2000.

With his outstanding expertise and visionary ideas, he shaped our company and made it what it is today. Even as senior partner, he remained connected to the company, supported its strategic direction and provided valuable impetus with his experience.

We are not only losing an exceptional entrepreneurial personality, but also a person who has always accompanied us with his appreciation, care and social responsibility. He will remain unforgotten.

Our sincerest sympathy goes to his family and all those who were close to him.

In silent memory

The management and employees of

LANG GmbH & Co. KG in Huettenberg

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.
