Powder Metallurgy
Powder metallurgy is a processing method for making various products by using metal powder as a raw material, pressing and sintering. The powder metallurgy process consists of three main steps. First, the main material is decomposed into a large number of fine particles of powder; then, the powder is placed in a mold cavity and a certain pressure is applied to form a powder blank having the desired part. Finally, the powder blank is sintered. Further processing is carried out for the needs of individual parts.

Raw materials (ingredients):
Mixing according to customer needs.
Forming:
Forming goods according to demand and conducting a rigorous review
Sintering:
Under the protection of nitrogen hydrogen (NH3) gas, the temperature is 800 ° (bronze) ~ 1150 ° (stainless steel) sintering, the sintering time is about 4HR (depending on the workpiece material).
