What is an injection mold?

      Plastic molds are tools used for processing the molding of plastic products, enabling mass production by imparting specific shapes and precise dimensions to plastics. They are widely applied in industries such as automotive, home appliances, and electronics. The core structure includes moving molds, fixed molds, as well as systems for pouring, temperature regulation, and ejection. The molding processes are categorized into six types: injection molding, compression molding, extrusion molding, blow molding, vacuum forming, and high-foaming polystyrene moldingMolds are adapted to different materials based on process variations: injection molds are suitable for complex thermoplastic products, compression molds are primarily used for thermosetting plastics, and extrusion molds produce continuous profiles such as pipes.

        Mold materials must possess heat resistance, wear resistance, and high polishability, commonly using carbon tool steel or alloy steel. For corrosive plastics (e.g., PVC, ABS), corrosion-resistant steels like martensitic stainless steel are employed. Design considerations include parting surface precision, structural component tolerances, and gating system optimization, while computer-aided technology enhances parameter efficiency matching molding machines
