China Mold Ejector Pins manufacturers Core pin is a general term for parts used to process the inner surface of molded plastic products. It is usually used to shape the inner hole or cylindrical shape of the product. The choice of core pin is mainly based on the shape of the molded product to specify the shaft diameter, overall length, and step shape. If necessary, it is necessary to process the shape of the tip and the shape of the shoulder. Sometimes in order to facilitate the exhaust of the slender structure of the formed product (such as ribs, cylinders, etc.), core pins are also used. Core pins are small, cylindrical components used in the injection molding process to create the innermost features of molded plastic products. These features may include holes, slots, threads, or other complex shapes that are integrated into the design of the final product. Core pins are usually made from steel or hardened alloys that can withstand high temperatures and pressures, and they are typically inserted into the mold cavity prior to injection. During the molding process, the plastic material is forced around the core pin, forming the precise shape of the internal feature. Once the part is complete, the core pin can be removed, leaving behind a highly detailed and accurate internal surface. Core pins are an essential component of many modern injection molding processes, helping manufacturers create complex, high-quality plastic parts quickly and efficiently.
