Metal Injection Molding

Metal Injection Molding (MIM) is a revolutionary new technology that combines plastic injection molding, polymer chemistry, powder metallurgy technology, and metal material science. It was published by the American company ParmaTech in California in 1973.

MIM technology uses ultra-fine metal powders and binders to produce injection molding resins through mixing, granulation processes, which are injected into high-precision special molds, and then processed by dewaxing and sintering processes to quickly produce high-density, High-precision and complex-shaped metal parts. Finally, according to the product function and specification requirements, if necessary, perform the second processing, such as heat treatment, surface treatment, etc.

Compared with traditional industry and powder metallurgy, MIM technology has the advantages of fewer processing procedures, no cutting or less cutting, and high economic efficiency. In addition, MIM can mass produce small workpieces with high precise dimensions and complex shapes and overcome traditional difficulties.

Process / Component Characteristics

High-Complexity Components: Metal Powder Injection can produce metal parts with special and complicated shapes.
High-Precision Components: In terms of dimensional accuracy, MIM parts are far superior to lost-waxing casting, die-casting and cold forging.
High-Quality Components: MIM components are composed of fine metallographic molecule crystals and relatively high sintered density products. These are corrosion resistance, surpassing traditional powder metallurgy, lost-waxing casting and die casting.
Can be produced in batches: Batch production times are much shorter.
