Metal injection molding technology in detail

Author:



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.

MIM products usually have the following characteristics

The most suitable wall thickness for MIM is no more than 6mm. Thicker outer wall is acceptable, but the cost will be increased due to the longer processing time and extra material used. In addition, u

What is the density and strength of MIM products?

The density of a typical MIM is theoretically higher than 98%. Specific density characteristics depend on the choice of material, but it is very close to precision materials.

The market competition pattern of 3D printed metal powder may change

The market competition pattern of 3D printing metal powder will change as more companies enter or increase their production and R & D efforts in the field of metal powder. In 2016, GKN, Oerlikon and Alcoa made active strategic plans.

Rich variety of raw materials, and the variety of domestic powder metallurgy products has been expanded

In terms of raw materials, at present, the main raw materials of powder metallurgy in China are not only reduced iron powder, electrolytic copper powder, etc., and domestic production of atomized iron powder, stainless steel powder, high-speed steel powder, coated powder and various element metal MIM powder, Ceramic powders can basically meet the needs of domestic production of high-strength parts, and can also produce raw material powders for special purposes, which greatly expands the variety of powder metallurgy products, but there is still a large gap in quality and variety from abroad.
