Powder metallurgy injection molding (MIM) technology
, originated from the field of plastic injection molding, is an innovative powder metallurgy near-net forming process. It integrates multidisciplinary knowledge such as plastic molding technology, polymer chemistry, powder metallurgy technology and metal materials science. Through MIM technology, metal powder can be injected into blanks using molds, and then through the sintering process, high-density, high-precision and complex-shaped three-dimensional structural parts can be quickly manufactured.
Core technical features
MIM mixes metal powder with a binder and then injects it into a mold, and then obtains high-precision and high-density parts through degreasing and sintering processes. Its core advantages include:
High precision: It can produce metal powder with a particle size of 2-15μm, and the relative density of the product exceeds 95%;
High efficiency: The processing cycle of complex structural parts is shortened by 60% compared with traditional processes;
Material utilization rate: Compared with traditional processes, it is increased by more than 40%;
Scope of application: It is suitable for materials such as titanium alloys and stainless steel. The products are widely used in electronics, automobiles, medical and other fields.
Typical application cases
Consumer electronics: folding screen mobile phone hinges, micro motor parts;
Medical equipment: surgical instruments, implant components;
Automobile manufacturing: turbocharger blades, fuel nozzles;
New energy: A-pillar components of new energy vehicles achieve lightweight production.
Comparison of MIM technology and traditional powder metallurgy
In contrast, traditional powder metallurgy processes mainly refer to powder metallurgy pressing and molding, which is formed by gravity filling of powder in the mold and mechanical pressure extrusion. This technology is widely used in industrial applications, including cold closed steel mold pressing, cold isostatic pressing, hot isostatic pressing and warm pressing. However, since traditional powder metallurgy can only achieve bidirectional pressing up and down, it is mainly suitable for the production of two-dimensional columnar products, and it is incapable of manufacturing complex structural parts.
