How to deal with the flow pattern of metal insert injection molding

There are many kinds of product defects in metal insert injection molded parts, including overflow, insufficient filling, air bubbles, cracks, spray lines and weld lines, and so on. Metal stamping manufacturers have also summed up their experience in the actual production process, and can take correct and appropriate measures for different problems. This article mainly talks about what measures can be taken to deal with the flow pattern of injection molded parts. The jet flow pattern is a trace that curves like a snake along the flow direction from the gate. It is caused by the excessively high injection speed of the resin from the gate. 1. Enlarging the cross section of the firing or lowering the injection speed are optional measures. 2. Increasing the mold temperature can also slow down the cooling rate of the resin in contact with the surface of the cavity, which also has a good effect on preventing the formation of hardened skin during the initial filling stage.
