MIM Processing, also known as Metal Injection Molding, is a forming method that involves injecting a mixture of metal powder and a plasticizing binder into a mold. It's a manufacturing process used to produce complex metal parts in large quantities with high precision. This technology combines modern plastic injection molding techniques with traditional powder metallurgy processes, forming a new type of powder metallurgy near-net-shape technology. The MIM processing steps include mixing metal powder with a binder, granulation, injection molding, and then removing the binder through debinding and sintering to produce the final component.
This technology allows for the manufacturing of metal parts with complex geometries, including thin-walled structures and internal channels that are difficult to produce with traditional processing methods. MIM products have a uniform microstructure without the coarse crystalline structure and compositional segregation seen in casting processes, resulting in high-density products with mechanical properties significantly superior to those of precision casting and traditional powder metallurgy. Additionally, MIM products exhibit higher dimensional accuracy and surface finish compared to precision casting products, reducing the need for further processing.
Moreover, MIM technology offers high precision and density, high material utilization, and is suitable for large-scale mass production, thereby increasing production efficiency and reducing costs. MIM is applicable to a variety of metal materials such as stainless steel, titanium alloys, iron, high-density alloys, superalloys, and intermetallic compounds, making it widely applicable across multiple fields, including electronics, automotive, medical, hardware, and machinery.
