This is an introduction to "insert injection molding processing" from Sanyo Metal Industries, a manufacturing company specializing in precision metal pressing.
■ "Insert Injection Molding Process" At Sanyo Metal Industry, we primarily engage in thermoplastic insert molding using vertical rotary molding machines. □ "Vertical Insert Molding" refers to a method where parts such as pressed items are inserted into a mold, the mold is closed, and resin is poured in, thereby integrating the resin with the pressed items. This allows for the creation of products that do not require assembly or products that have higher precision than those assembled afterward. Additionally, various items can be used as insert components, including conductors such as terminals (electrodes, connectors) and busbars (bus bars) made of copper or brass, as well as metal parts like collars, bushes, spacers, meshes, and nuts. The vertical rotary molding machine is specialized for this insert molding process, and by preparing two lower molds for the work being done, it can shorten the time for both the insert process and the injection molding process. ***If you are interested, please feel free to reach out.***

basic information
■Molding and Resin At Sanyo Metal Industry, insert molding is primarily performed by operators who work on the molding machines to carry out the insertion of components. This allows for the precise insertion of complex components or multiple parts, enabling the production of high-quality products. Regarding insert components, it is possible to use pressed parts, as well as metal cut parts and molded parts. Of course, we also accommodate standard injection-molded products. The resins used are mainly engineering plastics such as PBT, PPS, and PA, focusing on the production of automotive parts and electrical components. In particular, for automotive parts, we produce a significant number of important products related to switches, which are crucial for vehicle safety. ***Please feel free to contact us for prototypes or small lot production. We look forward to hearing from you.***
