    Advantages of Metal Injection Molding Technology

    Metal Injection Molding(MIM) is a new powder metallurgy process that can produce sintered components with high Density and complicated shapes without the need for machining. with its unique characteristics, MIM is capable of producing precise metal parts for a wide range of products, including automobiles, cellular phones, hand tools, dental instruments, pneumatic tools, power hand tools, surgical instruments, sporting goods, and laptop computers. The common materials used in MIM range from stainless steels and alloy steels to soft magnetic materials.

    Generally, MIM can achieve accuracy tolerances ±0.5%. It can obtain an even higher dimensional accuracy once MIM works with other processing methods.

    Table 1 and 2 show the comparison between MIM and other processes.
