What is MIM (Metal Injection Molding)

MIM is a new near-net forming processing technology for metal parts formed by introducing modern plastic injection molding technology into the field of powder metallurgy. It is a high and new technology that has developed rapidly in the field of powder metallurgy and industry in recent years.

The MIM process steps are: firstly, to meet the requirements of the MIM metal powder and organic binder in a certain temperature under the condition of the appropriate method mix into uniform feeding, then after granulating in heating plasticizing state with injection molding machine into a mold cavity to obtain billet, after chemical degreasing treatment or solvent extraction method, finally the sintering densification of the final product
MIM Technical Advantages:

The MIM can produce products with complex shapes, avoiding more secondary machining.

MIM products have high density, good corrosion resistance, high strength and good ductility.

MIM can combine 2 or more PM products into one MIM product, saving material and process.

MIM design saves material and weight.

MIM can be used to repeatedly crush the gate material after injection without affecting the product performance and high material utilization rate.

The MIM can form complex products through molds at one time, avoiding multiple processing procedures.

The MIM can make parts with complex shapes that are hard to machine.

The MIM can manufacture thin-walled products, the thinnest can be up to 0.2mm.

MIM products have better surface roughness.

MIM is more suitable for making fine blind hole and through hole.

The MIM greatly reduces the workload of secondary machining.

MIM can make small parts quickly and cheaply in large quantities.
