Occurs at joints of male and female modules, sliders, oblique pins, etc., which appear as uneven levels of joint surface, etc., due to improper mold clamping or problems with mold itself.

Filling and cooling processes of conventional injection molding are intertwined. When polymer melt flows, front of melt encounters a core surface or cavity wall with a relatively low temperature, and a condensation layer is formed on the surface. Melt continues to flow forward in condensate layer. As thickness of condensate layer increases, actual cavity flow channel becomes narrower. Thickness of condensate layer has a significant effect on polymer flow. Because thickness of plastic part is thicker in conventional injection molding, influence of condensation layer on injection molding is not great at this time. However, in thin-wall injection molding, when ratio of thickness of condensing layer to thickness of plastic part gradually increases as thickness of plastic part becomes thinner, this effect is great. Especially when sizes of the two can be compared with each other.
