Plastic Injection Molding is a manufacturing process used to create plastic parts by injecting molten plastic into a mold. The process begins with heating plastic pellets until they melt, then forcing the liquid plastic into a precisely shaped mold. Once cooled, the mold is opened, and the solidified part is ejected. This method is popular for producing large quantities of identical items, such as bottles, containers, and automotive components. It allows for high precision and can accommodate complex designs, making it a preferred choice in various industries, including consumer goods and electronics.
