Powder metallurgy forming
Powder metallurgy processing is a technique that forms solid parts by heating and pressing metal powder. The main steps include:
1. Preparing the metal powder, which is typically produced from metal raw materials through physical or chemical methods.
2. Mixing and pressing the metal powder into the desired shape of the billet.
3. Sintering at high temperatures to form solid connections between the powder particles, thereby enhancing the material’s strength and durability.
The advantages of powder metallurgy include the ability to manufacture complex-shaped parts, reduce material waste, and produce high-performance materials. It is widely used in industries such as automotive, aerospace, and medical devices.
