Why is powder metallurgy a low cost processing method?
 
Powder metallurgy has low processing costs, not because of cutting corners, but due to its short cycle advantage. The material utilization rate is relatively high, theoretically reaching over 99%. Due to the use of molds, when there is a certain batch demand for products, powder metallurgy can not only save on processing costs but also achieve very high productivity. For example, some products can produce tens of thousands of pieces in a day without any problem. 
 
Why do powder metallurgy products need to be immersed in oil?
 
Oil immersion can make powder metallurgy products have corrosion resistance, wear resistance, delayed life and service life. Through oil immersion, the sintered products are put into oil to soak. The oil is soaked into the pores of the products by capillary action, and the oil film formed plays a lubricating and friction-reducing role.
