DLC
Diamond Like Carbon
The antisticking property and hardness of DLC STS protect the mold from adhesive/abrasive phenomena induced by the processing of light alloys. DLC is used in shearing and bending of light alloys.
Main characteristics
Low friction coefficient, chemical inertness, high hardness
Main benefits
Resistance to abrasion, adhesion and corrosion. Recommended for shearing and bending light alloys.

Innovative solution from STS
Polishing + DLC STS
Risultato
Without coating it is impossible to mold, breakage of the printout is due to gluing phenomena. With polishing and DLC STS the sheet metal is bent and stretched with a breakage reject of 4%.
