What is the processing flow of powder metallurgy?

In recent years, the rapid economic development has driven the development of some parts manufacturers. Powder metallurgy is a manufacturing technology that integrates materials and parts forming, not only saving energy and efficiency, but also reducing pollution and saving materials. It has become the most advanced manufacturing technology in modern technology. What is the processing flow of powder metallurgy? Now let's follow the zhongwei Precision Editor to understand:

powder metallurgy

At present, the two processing technologies with good efficiency and effect in powder metallurgy are MIM and PM, also known as injection molding and compression molding. The advantages of these two processing technologies are as follows:

1: Powder Metallurgy Compaction Molding Technology (PM)

Powder metallurgy pressing forming technology (PM) is known as a new forming technology to solve high-tech and new materials. The products formed by pressing have the advantages of high performance, high precision, low cost, mass production, etc. MIM/PM is currently the focus of research and development in the powder metallurgy industry.

Process flow: powder raw materials - forming (normal temperature or warm compaction) - sintering - post-treatment (machining).

2: Metal Injection Molding (MIM)

Metal powder injection molding (MIM) is a new powder metallurgy near net shape forming technology, which introduces modern plastic spray forming technology into the field of powder metallurgy. It breaks through the limitation 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 or less cutting, higher product performance, and easy forming. It has become a prominent forming technology for modern manufacturing of high-precision precision parts.

Process flow: preparation of raw metal powder - powder shaped green block - sintering of green block - part processing.

It is believed that through the above introduction of zhongwei, we have roughly understood the powder metallurgy processing process. Due to the disadvantages of traditional pressure processing technology, such as huge equipment, expensive manufacturing price, easy oxidation of general process surface, and difficulty in completing the modeling of complex parts in large quantities, powder metallurgy technology is basically selected for the molding process of modern small and medium-sized parts.
