During the molding process of plastic products, any molding factor that reduces the molecular orientation of the polymer in the product can reduce orientation stress; any process condition that ensures uniform cooling of the polymer in the product can reduce cooling internal stress; and any processing method that facilitates demolding of the plastic product can […]

Fault analysis and troubleshooting methods Melt fracture: After the melt is injected into the cavity, a thin shell is first formed on the wall of the mold cavity. When this shell is squeezed by the subsequent melt during the filling process, it will cause melt fracture. Once a very thin shell is torn or moved,

Mold failure Since the surface of the plastic part is a reproduction of the mold cavity surface, if there are surface defects such as scars, corrosion, micropores on the surface of the mold, it will be reflected on the surface of the plastic part to cause gloss poor. If there is oily, moisture on the

When designing each injection molding product, we must first determine its mold opening direction and parting line to ensure that the core pulling slider mechanism is minimized and the influence of the parting line on the appearance is eliminated. 1. After the mold opening direction is determined, the product’s reinforcement ribs, buckles, protrusions and other
Several Basic Points To Be Mastered In Injection Mold Design Read More »
Plastic varieties: During the molding process of thermoplastics, there are volume changes caused by crystallization, strong internal stress, large residual stress frozen in the plastic parts, strong molecular orientation and other factors. Therefore, compared with thermosetting plastics, their shrinkage rate is larger, the shrinkage rate range is wider, and the directionality is obvious. In addition,

Black spots and impurities are important factors that cause scrap rates in normal production processes. They mainly affect the appearance of products and lead to product scrapping. Impurities and most black spots are foreign substances and have nothing to do with the raw materials themselves, while a small number of impurities and black spots are
