- The Working Principles of Plastic Injection Molding Machines
Plastic injection molding is a highly sophisticated process that involves injecting molten plastic into a mold cavity under high pressure, allowing it to cool and solidify into the desired shape. The plastic injection molding machine serves as the crucial tool to execute this method efficiently. The process commences with the feeding of plastic pellets into a heated barrel, where the material is melted. Once the plastic reaches the desired consistency, it is injected into the mold using a plunger or a screw mechanism. The mold, typically made of metal, is precision-engineered to create intricate and accurate shapes. After cooling, the mold opens, and the finished product is ejected, ready for use.
