First, an embossing tool must be made.
The embossing tool transmits the actual representation on the metal part. To do this, our toolmakers translate the two-dimensional paper design into a three-dimensional representation that is manually transferred to the tool. With artistically trained eye, our engravers work out finest details manually. In several steps, it is now hardened and made so resistant to the high pressure during the embossing process.
On a punching machine, the blanks made of brass or copper are now punched in a round or other external shape. For this purpose, the panels, which are delivered in a length of 2 m and a width of 1 m, cut into strips on a large cutting shear. These blanks are then processed on a screw press to medals, medals or badges.
The embossing tool is clamped on the screw press. An employee then lays down a blank he has just received from the stamping shop and stamps the medal, the badge or the medal in 2 or 3 passes. Depending on their size, the screw presses have a pressing pressure of 300 to 600 tons.
