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.
