A Plastic Cap Mould is a precision-engineered tool used to create plastic caps by shaping molten plastic into desired forms. Made from hardened steel or aluminum, essential parts include cavity, core, ejector pins, and runner system, which shape, cool, and eject the final product. Designed with high durability and precision, these moulds are used in injection molding techniques to produce uniform plastic caps. They are widely applied in industries such as food packaging, beverages, pharmaceuticals, and cosmetics, with varying dimensions and sizes for diverse applications.
