We designed an injection molding process based on the product analysis of the cover of a motorcycle side mirror. The purpose is to develop a design for the injection molding of the product, which is applied in the concept of Industry 4.0 that aims to have intelligent processes. We considered the clamping force, venting and cooling, gate, runner, and lifter for manufacturing a cover of a motorcycle side mirror without defects, warpage, and undercuts, but with an efficient process with the help of various sensors. The final design of the mold of the cover included lifters with an opening of 250 mm and a height of 630 mm. Multiple pressure and temperature sensors can be installed in the gate, runner, and cavity of the mold for manufacturing defectless products. The cycle time of the molding process was set to 20.5 s. The proposed design meets production needs in an effective time for manufacturing and leads to developing the designs of similar products.
