Generally speaking, thin-walled injection to injection speed to ensure full packing; and the wall thickness of injection parts need to slow speed to prevent the forming hole. But too fast speed easy to make raw material overheating. When the plastic gate or the exhaust is not HERSHEY'S, melt injection to speed through the gate, produce a lot of shear stress within the melt, melt with the mold cavity to exhaust air, even burning carbonized black.
