What are the differences between powder metallurgy injection molding and plastic spray molding

Metal powder injection molding is a new molding technology, which is the progress of industry and national level. Metal powder injection molding is actually a new powder metallurgy near net forming technology, which introduces modern plastic injection molding technology into the field of powder metallurgy.

The basic process of metal powder injection molding is as follows: first, the solid powder and organic binder are mixed evenly, granulated, injected into the mold cavity with an injection molding machine in the heating and plasticizing state (~150 ℃), solidified and molded, then the binder in the molding body is removed by chemical or thermal decomposition methods, and finally the final MIM parts are sintered and densified.

Metal powder injection molding technology is a product integrating plastic molding technology, polymer chemistry, powder metallurgy technology and metal material science. The mold can be used for injection molding blanks, and rapidly manufacturing high-density, high-precision, three-dimensional complex shape structural parts through sintering. This is a new revolution in the manufacturing technology industry. It can quickly and accurately materialize the design concept into products with certain structural and functional characteristics, and can directly produce parts in batches. Powder metallurgy injection molding

So far, more than 100 companies worldwide have been engaged in product development, research and sales of this technology. Therefore, information management technology has become the most active frontier technology field in the new manufacturing industry. It is a pioneer technology in the world metallurgical industry and represents the main direction of the development of powder metallurgy technology - metal powder metallurgy technology.
