OEM Plastic Injection Molding Secondary Molding

Ultra Thick Secondary Injection Molding is a specialized process in the field of injection molding, where high-density and thick parts with complex geometries are produced. This technique involves injecting a large amount of molten plastic material into a mold, which is designed to accommodate the thicker walls and sections of the part being manufactured.   The process typically consists of the following steps:   1. **Material preparation**: A suitable thermoplastic polymer, such as polycarbonate, polypropylene, or nylon, is prepared and melted to a uniform temperature for injection.   2. **Mold design**: The mold is specifically engineered to handle the thick sections. It may consist of multiple cavities or cores to accommodate the larger part dimensions and ensure proper filling and ejection.   3. **Injection**: The molten plastic is injected into the mold under high pressure, filling the cavities and creating the desired shape.
