Our advantages:
CIP Forming can eliminate the internal defects of raw sintered carbide blanks in particular. It can provide uniform density suppression products for the thick carbide strips/plate and special shape carbide products.
The internal stress can be removed through the cryogenic process to improve the microstructure.
The internal stress can be removed through the vibration process to improve the overall performance.
The service can be improved through the heat treatment process.
