In the injection molding production process of game controllers, weld marks are a common defect, usually caused by convection generated by the plastic during the flow process. This weld mark is formed when the front part of the molten resin from different directions cools down and fails to completely fuse at the joint. Although weld […]

As a cheap and high-performance engineering plastic, PPS is increasingly widely used in custom plastic injection molding. However, its molding characteristics have always been a constraint on its widespread use, and how to improve its burrs is also a problem explored by various molding departments. 1. Introduction to the characteristics of PPS engineering materials PPS, […]
Game controller injection molding manufacturer before molding, plastic must be fully dried. When materials containing water enter the mold cavity, silver ribbon-like defects will appear on the surface of the product, and even hydrolysis will occur at high temperatures, causing material degradation. Therefore, the material must be pre-treated before molding so that the material can […]
1. AR Glasses Injection Molding Products formation of white lines 1.1 Microscopic explanation of white lines: When plastic is subjected to tensile stress, cavitation stripe-shaped deformation areas are generated due to stress concentration. These stripe plane areas strongly reflect visible light, forming a silver-white luster on the surface of the material, commonly known as white lines. […]
