  • Sinter hardening in MIM

    What is Sinter Hardening? Sinter hardening is a process that produces martensite transformation during the cooling phase of the sintering cycle. That is the sintering and heat treatment of powder metallurgy materials are combined into one process, so that the material production process is more ...

  • Infiltration Process of powder metallurgy

    The powder compact is contacted with liquid metal or immersed in the liquid metal, the pores in the compact are filled with liquid metal, and the compact material or parts is obtained by cooling down. This process is called immersion. The immersion process relies on the external molten metal to w...

  • The importance of temperature control in MIM

    The importance of temperature control in MIM

    As we know, temperature control is the necessary key for all thermal processing, differnet materials requires different treatment, and even the same materials with the different density, also need modification on the temperature adjustment. Temperature is not only the important key for thermal pr...
