In the 3C industry, MIM has been used as a synonym for the iPhone's mobile phone card tray and camera ring metal protective frame. However, in addition to these, the precision parts in electronic cigarettes are also processed by MIM. The metal processing process on the market is probably not faster than the MIM powder metallurgy injection process. As long as the specifications and the measured size of the sample are confirmed, efficient and fast processing can be achieved. This advantage has been reflected in mobile phone card trays and camera accessories.

Product Trend

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

Among hardware accessories, MIM metal injection molding process is more efficient and precise than casting, machining, pressing and other processes. Because the products produced by metal injection molding are small and very fine stainless steel parts. Dimensional error, thin wall and hole thickness can achieve high accuracy. Complex part shapes, small sizes, and high yields are all advantages of the MIM process. At present, there are many related accessories in electronic cigarettes that involve MIM processing, such as cigarette holders, atomizer bases, shells, etc.

The powder metallurgy process is the current mainstream metal precision parts forming process. The more commonly used materials are: copper base, iron base, alloy, stainless steel, etc. Zhongwei Precision's "Titanium Alloy R&D Center" has been officially unveiled and put into operation. The mainstream molding processes of powder metallurgy are: MIM injection molding and PM compression molding. MIM injection molding technology is deeply loved by Apple and Huawei mobile phone precision parts due to its fast molding, high precision, stable performance and high material utilization rate. Parts such as trays and camera accessories are precisely formed.

MIM injection molding is not only widely used in mobile phone parts, but also very popular in the digital electronic cigarette industry. The powder metallurgy process can be seen in the entire digital electronic industry. Next, the application of MIM injection molding in electronic cigarette parts will be introduced. And the production process of MIM injection molding.

MIM injection molding helps the development of the electronic cigarette industry

At present, most of the digital electronic precision parts are formed by MIM injection molding technology. Not too bad, it has the effect of quitting smoking for smokers, which is good for health. MIM injection molding near-net molding technology can produce electronic cigarette precision parts with high efficiency, high precision and high performance, and help the rapid development of the electronic cigarette industry.

Advantages of MIM injection molding

MIM injection molding technology can produce very precise, small and complex parts. The parts produced have high precision, high hardness and strength. Even very complex precision metal parts can be mass-produced, and the material utilization rate is as high as 95%. The production cost is greatly reduced. Electronic cigarette metal powder injection molding is very suitable for MIM injection molding.

The fields of Zhongwei's precision production products include: digital electronics, electronic cigarettes, hardware tools, automobiles, home appliances, medical equipment, base station communications and other fields. At present, it has independently developed more than 5,000 powder metallurgy varieties, and cooperated with the Powder Metallurgy Research Institute of Central South University. Provide high-value, cost-effective production solutions and services.
