Some problems associated with Injection molding It’s a common coincidence that defects in injection molding arise from the mold design imperfection and inappropriate material compounding. Mold seal clearance, inappropriate clamping force and melting temperature along with non-uniform setting times play the major role in lowering the product quality. Besides, the usage of low grade polymer with inappropriate mass–mass ratio would also be a non-conformance in the production of a quality product. The following below are some of the problems that might arise in the production line. These researches are done by ExxonMobil Chemical Company for the material Polypropylene (PP).
