What Are Powder Metallurgical Components?

Definition: Sintered structural parts, also known as sintered structural parts, manufactured by powder metallurgy method with certain dimensional accuracy and capable of withstanding loads such as tension, compression, torsion, or working under friction and wear conditions.

Method: Press the formed and subsequently sintered parts in a uniaxial rigid mold at room temperature.

Application: Powder metallurgy structural parts are widely used in industries such as automobiles, agricultural machinery, textile machinery, garden tools, and electric tools.

The main advantages of powder metallurgy  parts are as follows:

1. When the part has irregular shapes, protrusions or pits, various heterogeneous hole shapes, powder metallurgy is easy to manufacture, and only a small amount of additional cutting processing is needed. It has obvious economic benefits.

2.When using powder metallurgy technology to produce mechanical parts, the material utilization rate can reach over 99.5%.

3. Due to the powder metallurgy process, parts are produced using molds, so the consistency of the contour, shape, and size of the parts is very good. However, there are many variables in various aspects during mechanical processing, making it difficult to maintain consistency.

4. Powder metallurgy technology can integrate the manufacturing of several parts, thereby saving future processing and assembly costs.

5. The material density of powder metallurgy parts is controllable and has a certain amount of connected pores. Generally, they are immersed in 5% -20% lubricating oil to provide some degree of self-lubrication, thereby improving wear resistance.

6.In powder metallurgy production, in order to facilitate the removal of parts from the press mold after forming, the working surface of the mold has a high smoothness, which makes the parts have adjustable smoothness. Powder metallurgy  parts can also undergo various subsequent treatments such as electroplating, coating, and heat treatment, just like mechanical parts.
