Technical Introduction: Injection Molding
We manufacture parts for eyeglass frames using injection molding. If you have any specific molding requests, please contact us.
The eyeglass frames and the parts used are made of two types: resin (plastic) and metal (metal), with the resin frame parts being manufactured through injection molding. 【Injection Molding】 ○ Melting the Resin Thermoplastic resin (plastic) is heated to its softening temperature. ○ Filling The softened thermoplastic resin (plastic) is filled into the mold under a pressure of 10 to 3000 kgf/cm². (It is pushed in.) ○ Ejection The filled resin is cooled and hardened in the mold before being ejected. In molding, in addition to the shape of the molded product, various conditions such as temperature, pressure, and cooling differ for each type of resin, which can require considerable time for condition setting. If you have a specific molding request, please feel free to contact us.
