MoldFlow analysis and parameters optimization of button seat injecting

摘要

The effect of the gate number and location, packing pressure and time on the filling cavity pressure, distribution of welding lines, warpage distortion quantity and shrinkage of the plastics part were analyzed by means of moldflow software for plastic electric button seat. Some possible defects in the products were predicted based on the numerical simulation. The optimal runner gate, the optimal technology scheme and the injecting process parameters were obtained. The research shows that the analysis results can provide the effective references for the injecting mold design, Practice has proved that Moldflow can be used to ensure the reasonable and efficiency of mold design.
