Weld lines on the injection molded part

Weld line is one of the plastic injection molding defects. It occurs when melting plastic material is injected into a mold, it flows through all parts of the mold. When a part design includes a hole, notch, or certain other features, the flow of plastic can be divided into two separate “flow fronts.” The material is flowing in two different streams, which flow around the feature and then come together. As the two flow fronts meet, the molten plastic from the separate fronts joins or “welds” together and often forms a slight line on the part, similar to a parting line mark. So how do Weld Lines affect the Part? And how to avoid it? You can find some tips in this video, please enjoy it。 Please also visit: www.dankemold.com to get more information.
