  Interpretation of the causes of injection mold problems​ (1) Ejection should be stable and balanced, such as the total number of ejector pins, the cross-sectional area, the demoulding slope, and the cavity surface should be smooth enough to avoid residual stress concentration and cracking caused by external force. (2) The structure of the part should not be too thin, and the transition part shou
