Weld Line Defect Analysis in Plastic Injection Molding

However generally, for molding simulation, its miles assumed that the melt enters the cavity at a specified glide fee or strain and uniform temperature. The simulation of the injection stage calls for correct shrinkage evaluation and complicated boundary conditions to ensure the frictional resistance of the component at the core. Progress has been made in those areas again, however nowadays there may be no simulation that may integrate these kind of effects. Injection molding is the maximum usually used production process for production plastic parts.
