Metal Injection Molding Advantages

Writer： admin Source： mdmmetal.com Date：2022-06-30

MIM technology combines the advantages of powder metallurgy and plastic injection molding, breaks the limits on the shape of the product of traditional metal powder press molding, and absorbs the advantages of plastic injection molding in large quantities and high efficiency of shaping parts with complex shapes. It has become a near-net shaping technology of manufacturing high quality precision parts with unmatched advantages compared to conventional powder metallurgy, machining and precision casting.

● Produce complex shape of small metal parts just like producing plastic pats, normal weight between 0.5~500 grams ;
● Molding complex parts equivalent the production of plastic products, such as external grooving, external thread, tapered outer surface, cross through holes, blind holes, key pin, stiffener plate, knurled surface and so on.
● Good surface finish(can be N6), high dimensional accuracy, the usual tolerance of ± 0.3% ~ 0.5%;
● Wide range for materials, products with high density (up to 95% to 99%), and homogeneous, high performance;
● Stable product quality, high production efficiency, can be automated, high-volume, large-scale production. Faster delivery than CNC machining and other processes.
