Injection molding faults in styrene copolymers and their

line s occur in injection molding when two flow fronts collide due to inhomogeneous orientation and anisotropy of particles (Wheeler 1999 2012; Santos et al. 2013). There are some studies performed about the po sible solutions to attenuate the defects caused by the use of metallic pigments. Optimization of the pr cessing conditions may be one of the solutions use to reduce the visual

Solution: Increase the amount of material being fed to the mold by adjusting the return stroke of the injection screw so that more material is transferred from the hopper system with each rotation of the screw. Adjust this setting until there is between a 0.3- and 0.6-cm cushion at the front of the injection …
