Plastic injection molding is a manufacturing process in which plastic materials are heated until molten and then injected into a mold where they cool and solidify into the desired shape. It is suitable for mass production of precise and complex plastic components. Common applications include electronic housings, automotive parts, and household appliance components. This method offers fast cycle times, dimensional stability, and high repeatability. Various thermoplastics such as ABS, PP, and PC can be selected based on requirements. While mold costs are relatively high, the cost per unit is low, making it ideal for medium to large volume production. When combined with multi-shot systems and automation, it enables highly efficient and high-quality mass production.
