Detailed introduction of metal injection molding technology

Metal injection molding is a combination of powder metallurgy and injection molding technology, which breaks the product shape and strength constraints of traditional powder metallurgy, also breaks the strength constraints of die-casting molding, breaks the data flow constraints of stamping die molding, breaks the mass production constraints of precision casting and the high cost constraints of turning parts.

Metal injection molding uses fine metal powder, which is mixed with the binder through the mixer to obtain a quasi-plastic mixture. Through the injection molding machine, the world embryo is shot out, and then part of the degreasing and vacuum degreasing sintering are selected as the rough embryo. After heat treatment, mechanical processing, surface treatment and other procedures, the metal structure parts with high density, high precision and disorderly shape are reached. Most parts are protected from mechanical processing, and only heat treatment, polishing Electroplating and other treatment. MIM parts have the advantages of messy, small parts, uniform raw materials, high mechanical strength, thin wall, etc.

Metal injection molding products have the characteristics of disordered shape, fine size, high density strength and many automatic production. Metal injection molding can greatly reduce the complex procedures and costs of traditional metal processing. Therefore, small mechanical parts with disorderly shape, high fineness and high performance raw materials, such as 3C electronics, hand tools, remote control cars, locks, cars, clocks and watches, optoelectronics, weapons, biomedicine and other product fields can be highly developed.
