Cracks at the mold top are a common defect in injection molding that can indicate excessive tensile stress, improper cooling, or material issues. This article explains causes, detection methods using Moldex3D, analysis workflows, and practical remedies.
Injection‑molding engineers know that a single defect can turn a perfectly good part into scrap. One of the most dreaded issues is the – a thin, hairline fissure that appears near the part’s surface, usually at a high‑stress location such as a sharp corner, a sudden thickness transition, or a gate. moldex3d crack top

: Cracking often occurs where two melt fronts meet. The software evaluates the mechanical strength reduction in these regions to predict failure. Residual Stress Cracks at the mold top are a common
If "Crack TOP" refers to visual surface defects on the "top" side of a molded part, the following steps are used to diagnose them: Warpage Analysis One of the most dreaded issues is the
