What are the two basic methods used in metal powder injection molding?

In the process of metal powder injection molding, why should we use fine powder as the raw material? Usually, which are the two basic methods of zcmim powder metallurgy factory below for you to answer:

1) small particles, large surface area, the higher the surface, can improve the power of sintering of powder;

2) grain refinement, the increase of the coupling force between the particles, improve the strength of the body after the skim;

3) fine particle resistance, melt and binder in the flow is not easy to separate, easy to mix and injection.

Thermal and solvent are usually used. The solvent debinding in injection molding to form an open pore network and subsequent thermal debinding of decomposition product discharge with mass transfer channel for the decomposition products may form the inner pressure and the chances of debinding defects caused by, degreasing speed.

Metal powder injection molding technology industry

Metal powder injection molding as a kind of advanced manufacturing technology, combined with the powder metallurgy and plastic injection forming technology has the advantages of limitations, breaks through the traditional metal powder die pressing forming process on the shape of the products. Has become the main processing method of precision devices. Among them, the automotive industry accounted for a significant proportion of the MIM industry each year, the global sales of 15 billion U. s.dollars. In Europe, the proportion is 45%, in North America, only 20%, while in Japan, only 18%.

With the continuous development of MIM, MIM technology can system for the processing of different materials, from low alloy steel, stainless steel to difficult to machining high temperature alloy steel. Therefore, MIM may replace the traditional machining and casting process. Compared with the traditional metal processing, its main advantage is that, as a kind of near net shape forming process can produce complex shape parts, can maximize the preparing the final shape of the parts without subsequent machining or only need to use the least amount of machining; material utilization rate is high, suitable for mass production.

MIM parts are first applied to the small displacement diesel engines of Europe and the United States diesel light truck engine. Now this technology has been widely used in the global car, mainly for the production of fuel system components, such as the jet nozzle and the armature.
