Research Development
Powder metallurgy concerns with the production of powdered metal or of metallic objects by compressing a powdered metal or alloy, with or without other materials. Heating process is performed without melting, instead, it is to solidify and strengthen. Porite produces oilless bearings, and machinery parts using this technique. One of the advantages of using powder metallurgy is that no materials are wasted.
Since products can be molded instantly, production is efficient. There are numerous choices in designing shapes. For the material to be powder and oil, selecting plays an important role. The key of finding a suitable selection is the technical development of refining and combining. With the originality of testing machines Porite has been able to satisfy its customers for its high precision, high efficiency, and high quality products.

Development
SubstanceFPER45
@@@Traditionally, products that need wear resistance and high power are processed through osmosis carbon hardening, and high frequency hardening.
@@@When using PER45, hardened products which went through the process of sintering can be maintained, and also the cost can be cut.
