How many processes are there in powder metallurgy?

Powder metallurgy is not only a material manufacturing technology, but also a material processing technology. How many processes are there in powder metallurgy? Let's take a look at it with Zhongwei Xiaobian.

1： Process and process flow of powder metallurgy

Process 1: Metal Injection Molding (MIM)

Metal injection molding (MIM) is a new near-net forming technology of powder metallurgy, which is formed by introducing modern plastic injection molding technology into the field of powder metallurgy. It breaks through the limitations of traditional forming technology, and can not only form complex parts in large quantities and with high efficiency, but also has less processing technology, no cutting, higher product performance, and easy to form. It has become a prominent forming technology for modern manufacturing high-precision precision parts.

Process flow: preparation of raw metal powder - green block shaped by powder - sintering of green block - post-processing of parts.

Process 2: powder metallurgy compaction molding process (PM)

Powder metallurgy compaction molding process (PM) is known as a new process technology to solve high-tech and new materials. The products formed by compaction have the advantages of high performance, high precision, low cost, and mass production. At present, MIM/PM is the two molding technologies focused on research and development in the powder metallurgy industry.

Process flow: powder raw material - molding (normal temperature or warm compaction molding) - sintering - post-processing (machining).

To sum up, several processes of powder metallurgy have been told to you. I hope this article will help you. If you need to know more about relevant content, welcome to zhongwei Precision, we will have professionals to answer for you.
