MIM powder injection of polishing and plating knowledge school

MIM powder injection molding (www.zcmim.com) is a kind of new manufacturing technology combined powder metallurgy and plastic forming process. It is first to mix selected powder with a binder for MIM powder injection, then pelletized and injection molding the mixture as required shape.

The polymer reinvests the mixtures with viscous flow characteristic, contributing to forming, cavity filling and the uniformity of powder filling. Debinding binder after forming, then sintering green parts. Some sintered products may also want to do further densification, heat treatment or machining.

Sintered product not only has same complex shapes and precision as plastic injection molding products, but also has similar physical, chemical and mechanical properties to forging. The technology is suitable for mass production of small, precise, three-dimensional shape and complex metal parts required special performance.
