1, the freedom of geometric shape of parts is high, and metal parts with complex shapes can be produced by one-step molding like plastic products.

2.MIM products have uniform density and good smoothness. The surface roughness can reach Ra 0.80 ~ 1.6μ m, and the weight range is 0. 1 ~ 200g. The dimensional accuracy is high (0. 1% ~ 0.3%), and generally no subsequent processing is needed.

3. Wide applicable materials, wide application fields, high utilization rate of raw materials, high degree of production automation and simple working procedures, and continuous batch production can be realized.

4. The product quality is stable and the performance is reliable. The relative density of the product can reach 95% ~ 99%, and it can be subjected to heat treatment such as carburizing, quenching and tempering. The product has high mechanical properties such as strength, hardness and elongation, good wear resistance, fatigue resistance and uniform structure.

Metal powder injection molding combines the advantages of powder metallurgy and plastic injection molding, and breaks through the limitations of traditional metal powder molding process in product shape. At the same time, plastic injection molding technology can produce parts with complex shapes in large quantities and efficiently, such as various external grooves, external threads, tapered external surfaces, cross-shaped through holes, blind holes, concave tables, key pins, reinforcing ribs, surface knurling and so on.
