The results show that the gate for single point of two sides is suitable on thin-walled injection molding by numerical simulation. The results also show that the processing is very well for thin-walled injection molding by numerical simulation. 原文.
WebFirst, they carry resin to the mold via a runner. Because this allows some cooling and thickening of the resin, tab gates require a relatively large opening into the mold cavity. This, in turn, leaves a large tab to be trimmed, a process that can mar the finished surface. Second, the runner leading to a tab gate takes up real estate within the ... Web16 hours ago · Training gives processors knowledge to optimize the molding processes. This can result in avoiding costly processing strategies (or lack thereof) that needlessly increase part weight. 7. USE GAS ASSIST MOLDING . Gas assist is a process where nitrogen is injected into a thick part to hollow it out.
