Application of Metal Injection Molding Technology

MIM in the 3C industry has been used as the synonym of the mobile phone Cato and the metal protective frame of the camera ring for the iPhone. However, in addition to these, precision parts in electronic cigarettes are also processed by MIM. The metal processing process on the market is probably no faster than MIM powder metallurgy injection process. As long as the specifications and sample sizes are confirmed, efficient and rapid processing can be achieved. This advantage has been reflected in mobile phone cator and camera accessories.

In 2018, sales of high-end smartphones declined, and the MIM products used in smartphones were gradually decreasing. However, new advantages appeared in the electronic cigarette industry. Most of the metal parts in electronic cigarettes were processed by MIM. As a new product, electronic cigarettes are close to the taste of cigarettes, and are more conducive to the use of quitters than cigarettes. Although the policy on e-cigarettes is not yet fully mature, the number of users of e-cigarettes has increased significantly. At present, there are at least 20.8 million users of e-cigarettes worldwide. Consumer demand naturally leads to an increase in the number of products. As a MIM injection process that can achieve high efficiency processing, it is essential to apply it to the processing of electronic cigarette accessories.

Compared with casting, machining and pressing processes, MIM metal injection moulding process is more efficient and precise in hardware accessories. Because the products produced by metal injection moulding are very small and fine stainless steel parts. Dimension error, wall thickness and hole thickness can achieve high accuracy. Complex shape, small size and large output of parts are the advantages of MIM process. At present, there are many parts related to MIM processing in electronic smoke, such as cigarette holder, atomizer base, shell, etc.
