Mobile phone parts suppliers introduce the production process of metal injection molding (MIM)

Metal injection molding (MIM) is a new type of manufacturing technology that combines the respective characteristics of powder metallurgy and plastic molding technology. In the process of raw materials, we need to mix the powder to extrude and granulate, and then generate the required part : metal injection molding Nozzle, metal strap, mobile phone part.

The viscous flow characteristics of the polymer will help the filling powder to be filled evenly during the injection process. The injection part needs to be degreased in a vacuum degreasing furnace (to remove the binder), so the original blank needs to be put into a high-temperature vacuum sintering furnace to smelt the metal raw material. Real metal parts. In some cases, further densification treatment, heat treatment and mechanical processing are required to meet the final requirements. Sintered parts not only have complex shapes and high precision with injection molded parts, but also have similar physical, chemical, mechanical properties and forging processing, as well as similar physical, chemical, mechanical properties and forging processing.

In the traditional machining process, for mobile phone parts and other complex parts, mobile phone parts suppliers often divide a single part into multiple parts, which makes the assembly of parts easier than the assembly of individual parts and assemble them into original parts. Single part. However, MIM technology provides the opportunity to integrate parts into a complete single assembly, which can directly shorten or reduce the process, and further improve efficiency and reduce costs. Therefore, MIM technology is particularly suitable for small precision metal parts with complex and special performance requirements and mass production.
