Common defects of plastic Injection Molding and causes

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 walls too thick. Short shot: Short fill or short mould: Partial part: Lack of material, injection speed or pressure too low, mould too cold, lack of gas vents: Splay marks

INJECTION MOLDING: ‘Know Your Machine’ : Plastics …

Apr 23, 2014 · Evaluating overshoot can be done quite easily by setting the molding machine up to run “fill only” parts (short shots that contain the plastic that is injected into the cavity during first-stage injection only). Once you are producing “fill only” parts, take note of …

Short shots, troubleshooting | Moldflow Insight 2018 ...

A short shot is the incomplete filling of a mold cavity which results in the production of an incomplete part. If a part short shots, the plastic does not fill the cavity. The flow freezes off before the flow paths have completely filled. To ensure the finished part is of good quality, the part must also be adequately packed with plastic.
