Description (optional):
<p><a href="https://www.dgmfmoldclamps.com/causes-of-uneven-shrinkage-in-plastic-parts/">Uneven shrinkage in plastic parts</a> often results in uneven distribution of internal stress. If this stress exceeds the stiffness of the plastic part, it will cause warpage and distortion and affect the dimensional stability of the plastic part.</p> <p>Fast <a href="https://www.dgmfmoldclamps.com/coolings/">cooling</a> < slow cooling (reason: slow cooling molecules have time to arrange, so the shrinkage is large)</p> <p>As the <a href="https://www.dgmfmoldclamps.com/injection-mold-components/">injection molding</a> conditions are related to deformation, we must pay special attention to the injection molding and holding time, cooling time, injection molding speed, and mold temperature.</p> <p>Depending on the shape of the molded <a href="https://www.dgmfmoldclamps.com/mold-clamps/">product</a>, sometimes the deformation is smaller if the injection molding speed is fast.</p>
