metal powder injection molding technology

Metal powder injection molding(http://www.zcmim.com/manufactureequipment.shtml) (MIM) technology is introducing modern plastic injection molding technology of powder metallurgy and form a new type of powder metallurgy net-shape forming technology.Its basic MIM process is: first of all to practice, solid powder and organic binder evenly mixed after granulating in heating plasticizing state (~ 150 ℃) with injection molding machine injection mold cavity crystallized8), and then use the method of chemical or thermal decomposition of binder removal from the billet, the final results of sintering densification of the final product.Compared with the traditional process, with high precision and uniform organization, excellent performance, low production cost.

What are the best Chinese metal injection molding supplier?

Metal powder injection molding technology is a new type of metal powder metallurgy the modern plastics spray forming technology into the field of powder metallurgy forming near net shape forming technology. The basic process is: firstly, the solid powder and organic binder, uniform mixing, granulating after plastic state under heating (~150 C) for injection molding machine injection mold cavity forming method of curing, and then decomposed by chemical or thermal forming blank in binder removal, finally get the final product after Sintering Densification. 

Compared with the traditional process, which has the advantages of high precision, uniform structure, excellent performance, low production cost, its products are widely used in customized stamping parts, electronic and information engineering biological, medical, office equipment, automobile, machinery, hardware, watches, sports equipment, weapons and aerospace industries. At present, there are several Chinese best powder metallurgy supplier such as ZCMIM,Haimeige etc..

Why is the metal part of the metal powder injection molding injection molding it?

Metal powder injection molding (MIM) is a new type of powder metallurgy near net forming technology which combines the modern plastic injection molding technology with the traditional powder metallurgy technology. MIM products with high dimensional accuracy (+ 0.1% ~ + 0.5%), good surface finish (roughness 1 ~ 5 m), and the yield is very large. But the MIM process is more, there are certain technical barriers. Why MIM can't do a mobile phone in the frame structure / back cover larger?

First of all, MIM debinding and sintering will make the product size, product size, size deviation is larger, and not easy to skim;

Secondly, the majority of MIM stainless steel parts, although stainless steel anode, but still aluminum anode effect best (mainly because of the aluminum oxide layer by alumina composition, the formation of well ordered hexagonal tube structure, similar to the specular reflection effect, the color looks bright.

Nevertheless, there are still companies try to use MIM technology in the mobile phone / box cover, is the MIM technology to further tap! In general, at present, processing machine represents the phone boxes / cover in the high-end market; stamping represents a phone box / cover in the low-end market, the mainstream of MIM on behalf of mobile phone small parts and other metal parts.
