Definition
Metal Injection Molding or 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.
Basic process steps
Firstly, select metal powder and adhesives which meet MIM's requirements; secondly, take appropriate methods to compound the powder and adhesives into raw material evenly in certain temperatures;then do injection molding after granulating, and then after derosination processing, sintering densification into end item.
