Injection molding involves the high-pressure injection of melted plastics and resins into custom molds. These molds are typically made of steel and may have cooling or heating lines running throughout the mold to facilitate more precise temperature control. The plastic resin (in pellet form) is loaded into the presses’ barrel via overhead material handling lines or via vacuum tubes from a hopper/gaylord. The pellets are melted in the barrel, and then injected into the mold’s runner system where the melted resin travels into cavities in the mold. Once the material has cooled to a solid, the part is ejected from the mold with the assistance of ejector pins.
