Machining different materials makes the engraving process technically very difficult and requires a lot of experience. For identification marks with the highest demands for scratch resistance as well as chemical and thermal resistance, Lace uses machine engraving. The usual stresses in mechanical engineering particularly place high demands on this type of identification.

The Lacon Group works with a complete engraving system for machining two matt, aluminium matt and aluminium identification material as well as other engravable materials.
