Injection Moulding

These Are two Moulding Defects Molding Defects Alternative name Descriptions Causes Cooling is too short, material is too hot, lack of cooling around the tool, incorrect water temperatures (the parts bow inwards towards the hot side of the tool) Uneven shrinking between areas of the part Warping Twisting Distorted part Localized depression (In thicker zones) Holding time/pressure too low, cooling time too short, with sprueless hot runners this can also be caused by the gate temperature being set too high. Excessive material or thick wall thickness. Sink marks Sinks Mould In Clamp
