Preparation of tools
Our modern CNC-controlled engraving machines cut, with the aid of the CAD data which is prepared from the production drawing, outlines, surfaces and 3 D forms in unhardened tool steel. During this process, the first draft of the embossed stamp is generated which we refinish in many different ways by moulding and riffling it and sanding off fine miling traces. Now, we check it with a lead print and harden it. Relief engraving and artistic work are hand-made by our in-house engravers.
