Why is powder metallurgy trusted and selected by everyone?

Many people do not understand why to use powder metallurgy, because they do not fully understand the advantages of powder metallurgy, have not tasted the benefits, and still stick to the backward technical stage. Today, Zhongwei Precision will tell you some concepts of powder metallurgy.

powder metallurgy

Powder metallurgy is a technology that uses powder as raw material to manufacture materials or finished products through a series of processes. Generally, metal powder (or other non-metallic raw materials added) is used as basic raw material to manufacture powder metallurgy materials or powder metallurgy products through mixing, forming and sintering.

The reason why powder metallurgy is deeply trusted and selected by so many manufacturers is that it can break through technical difficulties that cannot be made or broken through by other processes, such as porous, sweaty, shock absorption and sound insulation materials and products, as well as metal plastic, bimetal composite materials and products. The most important thing is to save energy. It can directly produce products that meet the size requirements of finished products. It is very energy-saving, and the utilization rate of materials is up to more than 95%.

Summarize the advantages of powder metallurgy process:

1. No or very little cutting is required;

2. The material transfer rate can reach 97%;

3. The manufacturing tolerance of part size is small and reproducible;

4. The material composition is adjustable;

5. The surface finish of parts is good;

6. Strength and wear resistance can be improved through heat treatment;

7. For self lubrication or filtration, materials or products with controllable porosity can be provided;

8. It can manufacture parts with complex or peculiar shapes that cannot be manufactured by other metal forming processes;

9. Suitable for medium to large batch parts production.

Due to the advantages of powder metallurgy technology, powder metallurgy parts are now used more and more widely in all walks of life. More parts are used in chassis, body, interior, etc., with a very broad prospect. At present, there are more than 1000 kinds of P/M parts used in automobiles.
