 MIM (Metal Injection Moulding)

Metal injection molding offers a manufacturing capability for producing complex shapes in large quantities. The process utilizes fine metal powders (typically less than 20 micrometers) that are custom formulated with a binder (various thermoplastics, waxes, and other materials) into a feedstock.
The feedstock is fed into a cavity (or multiple cavities) of a conventional injection molding machine.
After the metal powder is removed, most of the binder is extracted by thermal or solvent processing, and the rest is removed as the component is sintered (solid-state diffused) in a controlled-atmosphere furnace. The MIM process is very similar to plastic injection molding and high-pressure die casting, and it can produce much the same shapes and configuration features. However, it is limited to relatively small (typically less than 250 grams), highly complex parts that otherwise would require extensive finish machining or assembly operations if made by any other metal-forming process.
Metal Injection Moulding combines the advantages of the large degree of design freedom that comes with plastic injection moulding with the excellent mechanical and thermal characteristics of metallic materials. Now a well matured and trusted process it is capable of producing high-precision metal components for a wide variety of industries including electronics, mobile phones, medical and scientific equipment. A good range of metals is available.
