Problems that occur in short shots are usually due to mold issues which can include improper gate size, incorrect placement of venting and/or mold temperature. Warping issues can be caused by incorrect mold temperature and gate location. Sink issues can be caused by part thickness and/or incorrect rib size, in addition to injection speed. Proper location of gates should be where they will impinge on a wall or pin. Shrinkage issues are usually caused by length of cooling time, mold temperature, melt temperature, in addition to back pressure setting.
