Injection molding machines have many components and are available in different configurations, including a horizontal configuration and a vertical configuration. However, regardless of their design, all injection molding machines utilize a power source, injection unit, mold assembly, and clamping unit to perform the four stages of the process cycle.
Injection molding is a highly automated production process for producing large quantities of identical items. Granulated or powdered thermoplastic material is heated, melted and then forced under pressure into a mold. Once in the mold the material cools, forming a component that takes on the shape of the mold cavity.
