Metal Injection Molding Process Applied in Sewing Machine Parts

Metal injection molding(http://www.zcmim.com/faq.shtml) technology was first introduced by national 863 plan, to produce high density, high precision, high strength, complicated 3D shape parts. It has the advantages of low cost, high efficiency, good consistency and good abrasion resistance, strong ability to resist high temperature, and easy to mass production. With the production of sewing machine industry as example, traditional production method is generally take cold extrusion process. Though its cost for blank is lower, it requires more than 200 times procedures, high artificial cost and low efficiency. Shuttle blank with metal injection only needs lathing once on each side, as much as 10 procedures can complete finish goods, saving more than 100 procedures than traditional process, greatly shorten the production cycle and save a large amount of labor.

MIM Technology

Metal injection molding technology is a set of plastic forming process science, polymer chemistry, powder metallurgy and metal material science and other disciplines through and cross product, the mold can be injection molded blank and by sintering rapid manufacturing structure parts with high density, high precision and 3D complex shape, can quickly and accurately will design thought to have certain structural and functional properties of products, and can directly produce a large quantity of parts and manufacturing technology industry a new change.

This technology not only has less conventional powder metallurgy process, without cutting or less cutting and economic advantages, and to overcome the traditional powder metallurgy products, inhomogeneous materials and mechanical properties of low, not easy to forming thin-walled and complicated structure of the shortcomings, particularly suitable to mass production of small and complex and has special requirements of metal parts.
