What if there is a dent in plastic products?
knowledge related to the thickness of each part of the product, insufficient internal pressure of the mold, insufficient mold cooling, deformation due to insufficient cooling time, in the process of producing the product, dent is the most frequent occurrence of bad phenomena. The plastic injected into the mold shrinks in volume during cooling. The early cooling part, that is, the surface is hardened first, and bubbles are generated inside. The so-called Dent, it is the slow part that produces a conspicuous concave surface in the direction of bubble contraction.
