With the continuous increase of domestic demand in China, it can be predicted that by 2015 China's mold industry will still have greater growth. The most common mold is the two molds, the so-called two molds, there are two main cavity, you can open the mold, you can also open the mold. Described under the framework of the steel cooling solution are:

1, quenching and cooling before the mold placed in boiling water for 30-60min, to eliminate 15% -25% quenching stress and stabilize the retained austenite, and then -60 ℃ conventional cold treatment;

2, the -120 ℃ cryogenic treatment, the lower the temperature, the residual austenite into martensite volume more, but can not be completely transformed, if necessary, retain a small amount of retained austenite can relax stress, play a buffer role, Play to ease the phase change stress; precision mold

3. After the cold treatment is completed, the mold frame is taken out and heated in hot water to eliminate the stress of 40% -60% cold treatment. After the temperature is raised to room temperature, the tempering should be promptly carried out. The stress of the cold treatment is further eliminated to prevent the cold treatment from forming cracks.

Die for cars, aerospace, daily necessities, electrical communications, medical products and equipment, as long as a large number of products will be applied to die production, mold and die is an integral part of the mold.
