metal injection molding with foreign development gap in China

Metal injection molding industry in China have been nearly 10 years of rapid development, but with foreign industry still exists the gap between the following aspects: (1) enterprises, small scale, economic benefits is a long distance with foreign enterprises.(2) the product cross, enterprise interacting each other, the competition is fierce.(3) the majority of enterprises lack of technical support, research and development capabilities, products is low, it is difficult to compete with foreign.(4) lack of again and obsession.(5) process equipment and supporting facilities behind.(6) products export, trade channels.

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.

Is There Any Limit for MIM Product’s Weight?

Like any other technology, MIM technology also have limit. Maximum weight for product is 240 grams (from economic point of view, general limit weight is less than 50 grams). Some geometric features will have problem too (ultra thick or thin section). ZCMIM will advice you suitable solution for the best design.

Which Kinds of Product can Apply Micro Injection Molding Technology?

After second time pressure, product density was 98%, and the linear shrinkage is 15% ~ 22%. Minimum ceramic injection molding parts size is 10 microns. Micro ceramic injection gear’s minimum weight is only 0. 5 mg. The smallest size for the micro metal injection molding is 50 microns. Micro injection molding is used for micro pump, micro gear, micro-turbine, minimum surgical miniature catheter..

Micro Injection Molding Technology

Germany began to study micro injection molding technology 10 years ago. But all the raw material are thermoplastic, whose minimum size has amounted to 0.2 um. Based on the study, Germany is researching micro injection molding and micro ceramic injection molding technology. The powders are average particle size 1 5 microns carbonyl iron powder, 4 ~ 5 microns stainless steel powder and 0.6 microns alumina powder. Binder has used since the mix of polyolefin/wax compounds with normal aldehyde compounds. The binders are mixed polyolefin, Wax compounds, Normal aldehyde compounds. De-binding methods on study have heating to remove organic matter, poly aldehyde compound de-binding method and supercritical carbon dioxide method.

What Kinds of Materials can be Used for Aviation Industry?

One kind materials for powder metallurgy is a special functional material, such as friction materials, antifriction materials, sealing materials, filtration materials and so on. It also has close relation with MIM process(http://www.zcmim.com/helps/mimprocess.html), which is mainly used for aircraft and engine auxiliary machinery, instrument and airborne equipment. Another kind of powder metallurgy material is high temperature and high strength structural materials, mainly used for important component for aircraft engine.
