Metal Injection Molding

Metal Injection Molding (MIM for short) is a new type of powder metallurgy near-net forming technology derived from the plastic injection molding industry. As we all know, plastic injection molding technology produces various complex shapes at low prices, but the strength of plastic products is not high. In order to improve its performance, metal or ceramic powder can be added to the plastic to obtain products with high strength and good wear resistance. In recent years, this idea has evolved to maximize the solids content and completely remove the binder and densify the green body during the subsequent sintering process. This new powder metallurgy forming method is called metal injection molding.

1. Definition of metal powder injection molding

Metal powder injection molding (MIM) is a new type of component that introduces modern plastic injection molding technology into the field of powder metallurgy and integrates plastic molding technology, polymer chemistry, powder metallurgy technology and metal materials science. near-net shape" technology. It can use molds to inject blanks, and quickly manufacture high-precision, high-density, three-dimensional complex-shaped structural parts through sintering, and can quickly and accurately materialize design ideas into products with certain structural and functional characteristics, and can be directly processed. Mass production.

MIM technology combines the technical advantages of plastic injection molding and powder metallurgy. The main disadvantages of low performance, thin wall, difficult to form and complex structure, suitable for mass production of small, precise, complex three-dimensional shape and the manufacture of metal parts with special requirements.

MIM process has become a new type of "near-net-shape" technology with rapid development and promising prospects in the field of international powder metallurgy, and is praised as the "hottest part forming technology" by the industry today. According to the "Advanced Manufacturing and Assembly Survey Report" released by McKinsey in May 2018, MIM technology ranks second in the world's top 10 advanced manufacturing technologies.

2. Development policy of metal powder injection molding industry

The metal powder injection molding industry is one of the high-tech industries prioritized by the state. China has promulgated a number of important policy documents and laws and regulations to encourage and support the development of this industry, providing support for the development of the metal powder injection molding industry.

3. Development status of metal powder injection molding industry

(1) Market size of metal powder injection molding

China's MIM market has grown from 4.9 billion yuan in 2016 to 7.93 billion yuan in 2020, with an average annual compound growth rate of 12.79%. It is expected that the MIM market size will reach 8.9 billion yuan in 2021.

(2) Quality classification of metal powder injection molding materials
