MIM,
is a metal injection molding (metal injection Molding, referred to as MIM) is a
kind of metal powder and binder plasticizer mixture was injected into the model
of forming method.
It is
the first choice of powder and binder are mixed, then the mixture was injected
to granulation forming shape. The characteristics of the viscous flow of the
polymer with mixture, and contribute to forming, mould filling and powder
packing uniformity.
After
the forming process, the binder is excluded, and then the sintered compact is
sintered. Some sintering products may also be further densification treatment,
heat treatment or machining. The product not only has the same sintering and
plastic injection molding products obtained complex shape and high precision,
and is physical, chemical and mechanical properties of the forging close.
This
technology is suitable for the manufacture of large quantities of production of
small, precise, complex three-dimensional shape and has the specific
performance requirements of the metal components.
