Metal powder injection molding is a branch of metallurgy and materials science. The process mainly uses metal powder as raw material and uses the method of “forming + sintering” to manufacture materials and products. It is a near net molding process to produce complex parts at a lower cost. According to the classification of materials, powder Injection can be divided into MIM(Metal Injection Molding) and CIM(Ceramic Injection Molding) categories.
Metal injection molding feed is a composite particle of fine metal powder with low oxygen content and good sphericity by adding polymer materials to make the powder uniform. It has high fluidity, high sintering density, high comprehensive strength, good toughness, mirror-like polishing effect and other properties. Metal injection molding feed is mainly used for metal injection molding products in mobile phone parts, wearable intelligent terminals, automobile parts, medical instruments, aerospace parts and other fields.
The parts prepared by MIM process are widely used in the fields of aerospace, automobile industry, national defense, electronic communication, medical treatment, machinery and so on. It has become a high and new technology in powder metallurgy and industrial field with rapid development in recent years. The global MIM market is expected to grow from $3.1 billion in 2018 to $4.5 billion in 2023.
China’s MIM market began to grow gradually since 2000. In just over a decade, the domestic MIM market has shown a relatively strong momentum of development. According to the statistics of Powder Metallurgy Association of China Steel Association, the domestic MIM scale exceeded 1 billion yuan in 2011, and the market scale reached 4.85 billion yuan in 2015, accounting for 35.23% of the global MIM market scale. In 2019, the domestic MIM market scale increased to 8.4 billion yuan, a year-on-year growth of 20%. The Chinese MIM market has developed into an important part of the global MIM market.
