Metal Injection Molding (MIM) is a process used to manufacture metal parts with complex structures and high precision. The molding process combines metal powder, injection molding and sintering technology to ensure that MIM parts have strict tolerances and excellent surface quality. In addition, selecting metal powders of different sizes and shapes and supplementing additives will produce different chemical and physical properties of MIM parts, and the binder composition of each powder particle will determine the stiffness of the final shape to promote the development of high-tech industries.
The Micro Metal Injection Molding process mixes extremely fine metal powders (typically less than 15μm) with a binder component, which consists of a primary wax material, a secondary thermoplastic polymer and other materials used. In this step, all extremely fine elemental or pre-alloyed metal powders are uniformly coated with a binder to achieve a wide range of properties to achieve the required flow characteristics for the next injection molding process.
Advantages of Micro Metal Injection Molding
The micro metal injection molding process has the following advantages, which makes it have great potential for application in the field of high-tech:
High precision: The size of parts produced by μMIM can reach micron level, which can achieve complex geometric shapes and high-precision details.
Production efficiency: Compared with traditional processing technology, μMIM can efficiently produce a large number of identical parts, which is suitable for mass production.
High material utilization rate: The material waste rate of this process is extremely low, which helps to reduce production costs and environmental impact.
The micro metal injection molding process has shown great potential in promoting the development of high-tech. As this technology continues to mature, it will play a more important role in many fields such as medical, electronics and industry. I believe that in the near future, micro metal injection molding will become an indispensable part of the high-tech industry, promoting global scientific and technological progress and industrial upgrading.
