Specific manufacturing process of powder metallurgy

With the continuous development of national industrial technology, the traditional casting process of powder metallurgy has been unable to meet the needs of modern industry, so now the parts and components used in many fields need to be produced by high-tech means, however, powder metallurgy is this high-tech process. So what is the operation process of powder metallurgy? The following is the share of zhongwei precision editor.

Specific manufacturing process of powder metallurgy process:

1. There are two kinds of milling methods: mechanical method and physical-chemical method. However, mechanical method can be divided into: mechanical crushing and atomization; Physical and chemical methods can be divided into reduction method, atomization method and electrolysis method.

2. The powder metallurgy molding is a green block in a certain state. The purpose of forming is to produce the required shape and size of compacts. The forming methods are divided into pressure forming and non-pressure forming.

3. Sintering is a very important step in powder metallurgy process. Sintering can be divided into unit system sintering and multiple system sintering. The sintering temperature and melting point of solid state sintering of unit system and multiple system are lower; In addition, there are also special sintering processes such as loose packing sintering, melt leaching and hot pressing.

4. The products after sintering can be treated in many ways according to requirements. Forging can also be applied to the processing of sintered powder metallurgy materials.

To sum up, it is an introduction to the specific operation process of powder metallurgy. I hope you can understand the operation process of powder metallurgy through this article. If you need more information, please pay attention to the official website of zhongwei Precision.
