What is the basic flow of powder metallurgy process?

Powder metallurgy is a new kind of near - net forming technology. The required mold is formed by melting, heating, injecting and pressing metal powder. For special materials such as hard to process, refractory metals and high alloying, traditional processing methods are not feasible. Powder metallurgy has become a major processing and production method, especially in high precision gear and automotive parts. So what is the basic process of powder metallurgy? zhongwei Precision to introduce:

Step 1: Make the raw material into metal powder

A step in the preparation of a metal powder from a raw material by oxide reduction and mechanical methods.

Powder metallurgy

Step 2: Make blank powder

According to different product requirements, wet, dry and semi-dry powder is mixed evenly in a certain equal proportion to make green powder. The proportion of powder must be controlled well.

Step 3: Mold forming

The mixed raw powder is placed into the corresponding powder metallurgy molding die and the desired shape is formed by pressure molding or non-pressure molding.

Step 4: Sintering of powder metallurgy model products

The die model can be sintered by either multiple sintering or unit sintering to form the physical and mechanical properties required for the final part product. Powder metallurgy sintering process is the most important step in the whole process, and also the decisive process to determine the product properties.

Step 5: Sintering follow-up details

For products with high precision requirements, follow-up finishing, oil immersion, electroplating or small processing, heat treatment and other details should be carried out after the product through the sintering process to ensure that the product has better stability and hardness.

These are the questions about "What is the basic process of powder metallurgy?" ". Of course, powder metallurgy shouldn't stop there. Basically, powder metallurgy technology has covered all walks of life. If you have powder metallurgy related needs, welcome to consult zhongwei precision powder metallurgy mim.
