Tungsten Steel Production Process

HIP (hot isostatic pressing)

1, HIP Treatment Summary

Powder metallurgy method is easier than the melting alloy is formed within the pores, although with advances in manufacturing technology, has been able to produce almost no pores, but at high pressure processing conditions of use, although the internal micropores is small, can make carbide tools damaged. In addition, for users that require extremely high reliability requirements, can be found in the existing material based on the increase HIP treatment, especially for the semiconductor industry uses progressive die, pin punch, encapsulation molds blanks, require a high material stability. Daijie the company 20 years ago to eliminate the use of the most advanced internal micropores HIP equipment to produce no internal defects of high quality carbide.

2, HIP Treatment Principle

HIP treatment is the principle of high temperature and pressure carbide placed in an argon atmosphere, so that destruction of the internal micropores, by changing the working conditions, HIP can significantly improve the bonding strength of carbides in the less binding agent timber species HIP better show results.
