The powder metallurgy process existed for more than 100 years, it is one of the general metal-forming processes performed by filling the mixed metal powder into the mold for forming the near-net-shaped products. Over the other metal forming technology, such as metal casting or forging, this process is in the advantages of material utilization, shape complexity, controlled porosity, etc. Nowadays, powder metallurgy is a mature metal process and applied for numerous industries, you can find powdered metal products around your life such as automotive/motor components and household appliances. It also will become an important process for manufacturing lightweight parts in the future trend.
