Metal injection molding (referred to as MIM) is a technology combining powder metallurgy and injection molding, which breaks through the traditional powder metallurgy product shape and strength limitations, also breaks through the strength limitations of die casting, breaks through the material flow restrictions of stamping molds, and breaks through precision. Mass production restrictions for casting and high cost constraints for turned parts.

Metal injection molding (MIM) uses fine metal powder, mixed with a binder through a kneader to obtain a pseudoplastic mixture, shoots embryos through an injection molding machine, and then uses partial degreasing and vacuum degreasing to sinter the rough embryos. After heat treatment, mechanical processing, surface treatment and other procedures, metal parts with high density, high precision, and complex shapes are achieved. Most of the parts are avoided from mechanical processing, and are only heat treated, polished, and electroplated. MIM parts have the advantages of complex, small parts, uniform material inside, high mechanical strength, and thin walls.

The finished product of metal injection molding has the characteristics of complicated shape, precise size, high density strength and mass automatic production. Metal injection molding can greatly reduce the complicated procedures and costs of traditional metal processing. Therefore, small mechanical parts with complex shapes, high precision and high performance materials such as 3C electronics, hand tools, remote control cars, locks, automobiles, clocks, optoelectronics, weapons, biomedicine, etc. can be highly utilized. Therefore, Metal injection molding manufacturing will be your necessary choice when developing finished products.

Technical advantages of metal injection molding (MIM):

(1) Parts with complex shapes can be formed at one time, reducing the cost of secondary processing.

(2) The surface roughness is good, and it can be applied to watch parts and decorations that value appearance.

(3) Mechanical properties are better than traditional powder metallurgy products.

(4) High density and easy plating.

(5) Parts can be efficiently mass-produced in a multi-cavity manner.

(6) Almost all metal materials that can be made into fine powder can be used in the metal injection molding (MIM) process.
