Product Description
Cemented Carbide Die for Cold Heading Stamping Mould Punching
Grand Sea Cemented Carbide produced Carbide Cold Heading Dies is used on the cold forging machine, making the materials cutting, reforming, forming to the mould.
Our advantages:
1. Made by virgin raw material.
2. HIP (Hot Isostatic Press) sintering ensures the stable microstructure, the service life time is longer, die change is less, can improve the working & production efficiency.
3. We also supply carbide dies with coarse grain size, which has high impact resistance ability and can be used to make big size carbide dies.
