In our previous article, we discussed the main causes of stress marks in plastic molding products. Now that we understand the causes, it's imperative to explore ways to minimize internal stress during the production process. With guidance from the engineers at Dongguan Yize Mold, the solutions are outlined below:

In the field of injection molding, when we closely observe finished products made of materials such as ABS, PP, and PC, it is not uncommon to find white or shiny marks on their surfaces.

In the field of injection molding, residual stress, the sum of internal stresses that remain unrelaxed after a product is ejected from the mold, is a key factor affecting product quality.
