1. We coat our punch with TiN by PLATIT coating equipment which made by Switzerland, the color of TiN coating is golden yellow.
2. Thickness of TiN coating is 1цm~6цm, can reduce the friction force of punch between sheet and die, increase tools' life in 2~6 times.
3. TiN is a basic coating, and moderate in price, the surface of tools is more sooth, very good for punching Al sheet, not easy to sticky the punch.
4. TiN coating is cheaper than TiCN. You can choose TiN coating for countersink, emboss, sheetmarker, punch and shear, rolling rib, punch, punch insert etc.
