Injection molding is a manufacturing process that involves injecting molten plastic into a metal mold cavity (the mold rotates and heats continuously along two vertical axes, causing the plastic to spread evenly under gravity and heat), followed by cooling and solidification to form a plastic product. It is widely used in the automotive, electronics, medical, and home furnishing industries. The process includes six main stages: mold design, material preparation, mold processing, injection molding, cooling and mold opening, and finished product inspection. Precise control of parameters such as temperature and pressure is crucial to ensure product quality. Mold manufacturing utilizes CNC machining centers and EDM machines, achieving an accuracy of ±10μm (1 mil) and supporting two-color/multi-color molding technologies.
This process improves efficiency through Mold Flow Analysis 4.0 and dynamic variable mold temperature technology, reducing product shrinkage rate to below 0.5%. Material applications include new engineering plastics such as carbon fiber composites. In the automotive parts sector, a 48-cavity hot runner mold has been implemented for one-time molding of 12 functional structures. Processing companies are equipped with 30-380 ton injection molding machines and are ISO certified, capable of producing high-precision gears, smart home components, and other products. Digital twin technology is driving innovation in precision manufacturing.
Injection molds are tools used to produce plastic products, giving them a complete structure and precise dimensions. Injection molding is a processing method used for the mass production of complex-shaped parts. Specifically, it involves injecting molten plastic under high pressure into a mold cavity using an injection molding machine, where it cools and solidifies to obtain the molded product.
