Abstract: Injection molding is widely used in high-end fields such as precision instruments, biological
genetic engineering, information communication, and aerospace. The yield of precision injection molded
products is severely constrained by defects caused by warping, shrinkage, cooling, and other factors during
the molding process. The improvement of product defects and quality control methods have become
