Every step in the production process of cemented carbide molds is critical and directly affects the quality and performance of cemented carbide molds after production. What is the production process of cemented carbide molds? The technical engineers of Renqiu Hengrui Cemented Carbide Co., Ltd. have summarized the following very important key processes based on more than 50 years of production experience:
1: Spray drying of raw materials: The mixture is prepared under a fully closed loop mirror using high-purity nitrogen protection, which effectively reduces the possibility of oxygenation of the mixture during the preparation process, and can effectively ensure the purity of the material and prevent the soiling of the material.
2: CIP (Cold Isostatic Pressing): Using a 3000Mpa isostatic press, it can effectively eliminate the occurrence of pressing defects and provide a good guarantee for pressing blanks with uniform density.
3: SP low-pressure sintering strength: The maximum sintering pressure can reach 100 kg, which effectively eliminates the internal gaps in the alloy body, thereby obtaining a well-densified, high-hardness, high-strength cemented carbide mold. The advanced temperature control system can effectively reduce the possibility of quality fluctuations in carbide molds.
4: Cryogenic treatment: Effectively improve the microstructure of the cemented carbide mold, so that the internal stress of the cemented carbide mold can be effectively eliminated.
5: Analysis and testing: The national testing center can conduct comprehensive various performance tests and adopt ultrasonic flaw detection methods to ensure the stable quality of cemented carbide molds.
