Electroplating of Press Tools
Generally hard chrome plate used:
- high hardness (1000HV)
- good corrosion resistance
- low friction against steel
- 0.5mm thickness limit due to residual stress
- low temperature treatment (55-60oC)
- deposited from acid plating solution (CrO3 in H2SO4)
Wipe die which produces flanges; Cr-plated inserts
