Injection molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. The injection molding machine IMM can be considered to have two halves: the injection unit, where the material is prepared for injection into the mold, and the clamping unit, where the injected plastic is captured in …
Injection molding is based on the principle of using a mold to shape molten material into a desired form. The process begins with the preparation of the mold, which consists of two halves— the cavity and the core. These halves are precisely machined to create the desired shape and features of the final part.
