Plastic processing refers to the methods used to shape and form plastic materials into usable products. This involves several techniques, including injection molding, extrusion, and blow molding. Each method has its own specific applications, allowing manufacturers to create everything from simple containers to complex automotive parts. The process typically begins with raw plastic pellets, which are heated until they become pliable. Once softened, the plastic is shaped using molds or other tools, and then cooled to harden into the final product. This versatility makes plastic processing essential in various industries, including packaging, automotive, and consumer goods.
