Metal powder as raw material, pressing and sintering method for processing a variety of products made ​​from

Powder metallurgy (Powder metallurgy), is a kind of metal powder as raw material, pressed and sintered products made ​​from a variety of processing methods. Powder metallurgy process  polycrystalline diamond  three main steps, first, the main component material is broken into many small particles of powder; Then, the powder into a mold cavity, subjected to a  Polycrystalline diamond e, to form a desired part  cutting tools  compact size; Finally, the sintered compacts. PM parts production process essential advantage is that the final shape forming capability with parts and materials utilization is high.
