How to Stop Flash Plastics Technology

Jul 01, 2004  First-stage injection fills 92% to 99.9% of the part, but this stage must end before the cavity is full. At the minimal pressure level for the second phase it is easy to inspect whether the part is a short shot at the end of first-stage injection. If there is flash on the short shot, we can focus on parameters affecting first-stage injection.
