Drawing

The drawing technology allows manufacturing hollow pieces starting from metal sheets or flat strips. Special matrixes and punches forge the material into the desired shape.

Strip-fed progressive dies are used for dishing, otherwise disk-fed or blank-fed compound dies are used.

Drawn pieces usually feature a low reduction in the thickness of drawn parts and walls free of cracks, which are due to material deformation, and high repeatability.

The use of suitably structured materials to be drawn, high-performance lubricants, special surface coatings of matrixes and punches, as well as a proper forging sequence and a high corporate know-how are the fundamental elements of this major manufacturing process.
