Powder metallurgy process technology for preparing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, after forming and sintering, to manufacture metal materials, composite materials and various types of products. Powder metallurgy is similar to the production of ceramics, both belong to powder sintering technology. Therefore, a series of new powder metallurgy techniques can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving the problem of new materials and plays an important role in the development of new materials.
Powder metallurgy includes milling and products. Milling is primarily a metallurgical process. Powder metallurgy products are often far beyond the scope of materials and metallurgy, and are often interdisciplinary (materials and metallurgy, mechanics and mechanics, etc.) technology. In particular, modern metal powder 3D printing integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science, and laser technology, making powder metallurgy product technology a modern comprehensive technology that spans more disciplines.
2.Powder Injection molding process
The plastic processing method in which the plastic is plasticized in the heating barrel of the injection molding machine and injected into the cavity of the closed mold by the plunger or the reciprocating screw to form the product. This method can process products with complex shapes, precise dimensions or with inserts, and has high production efficiency. Most thermoplastics and some thermosetting plastics (such as phenolic plastics) can be processed by this method. The material used for injection molding must have good fluidity in order to fill the mold cavity to obtain the product.
Since the 1970s, there has been a type of injection molding with chemical reaction, called reaction injection molding, which has developed rapidly.
3: The difference between powder metallurgy and powder injection molding
As we all know, powder metallurgy is an industrial technology for preparing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, after forming and sintering, to prepare metal materials, composite materials and various types of products. There are two types of powder metallurgy parts molding: powder pressing molding and powder injection molding. Do you know their relationship?
