MIM

The automotive industry: A major consumer of MIM parts The automotive sector has become a major consumer of MIM, and parts of high complexity are used in engines, gearboxes, turbochargers, locking mechanisms, steering systems and electronic systems, to name just a few. Rocker Arms for BMW engines An example is the roller following type rocker arm shown in Fig. 20. …

1.1 Mechanical polishing Mechanical polishing advantage is processed parts flat, high brightness.The downside is the intensity of labor is big, there is pollution, not suitable for complex polishing the MIM parts, and gloss can’t consistent, easy to rust.Suitable for processing is simple, small and medium-sized products. 1.2Chemical polishing Advantages of chemical polishing processing equipment is less investment, complex parts can …

Metal Injection Molding technology or MIM is a set of plastic forming technology, polymer chemistry, powder metallurgy technology and Metal material science and other multi-disciplinary mutual penetration and cross product, using the mold to the Injection forming and sintering ware rapid manufacturing high density, high precision, the structure of the 3D complex shape parts, can fast accurate materialized the ideas …

In the field of medical apparatus and instruments, the MIM (metal injection molding)process of medical parts with high precision and can satisfy the most sophisticated medical equipment accessories needed for the small, complex, high strength and performance requirements,MIM (metal injection molding)process has also been widely used in recent years, such as operation handle, scissors, tweezers, dental parts, parts of otology, …

Powder metallurgy is a metal powder as raw material, through pressure molding, sintering and subsequent processing of metal products, now can also ceramic forming, tungsten alloy forming, powder metallurgy is a machine with less or no excellent batch production method, can under the lower cost, making complex shape, high structure strength of the parts, under the low cost of mass …

The sintering Purpose-to increase strength & hardness of a green compact Carried out at a temperature below the highest melting constituent. Furnaces may be either the electric resistance,gasfired or oil fired type. Principal variables-temperature(generally within 70-90% of the melting point of metal or alloy),time(10min.-8 hours)&furnace atmosphere. Sintering process is concerned with -diffusion(surface of particles as temperature rises) -densification(decreases porosity,increase particle …

The minimum or maximum thickness on any parts mainly depends on parts of design and size。 Needs the most attention is the MIM technology in the process of forming parts could fully pouring。 For example, if the local thickness of 0.01 inches, it can fully populated, but if the thickness of parts across four inches length, it is not fully …

Metal Injection Molding (Metal Powder Injection Molding, or MIM) is a traditional Powder metallurgy technology and plastic Injection Molding technology of the combination of a high and new technology.MIM began in the late 1970 s, in the past the lack of proper powder and raw material price is too high, imperfect knowledge platform, the technology is not mature, people understand …

Complex shape parts, small size and large output, these are the advantage of the MIM process. These advantages make the MIM technology in the electronic digital products, small arms, watches, hand tools, orthodontics, automobile engine parts, electronic seal, cutting tools, and a large number of applications in the field of sports equipment. Before choosing the MIM process need to carefully …
