Study of High-Speed Plastic Injection Molding and its Mold Structure Characteristics

Abstract:

High-speed injection molding technology refers to the injection speed of rotating screw is about 500mm ~1000mm/s during the injection process. It is extensively used in the fabrication of thin and accurate products, for example, packing containers, CD or DVD disc-based panels, smart cards, optic fiber connecters, etc. In this paper, the advantages of high-speed injection molding technology on cost savings, product quality and productivity are presented firstly. Then the mold characteristics on strength, stiffness, precision, used material, heat treatment, the runner system, the venting system and the ejection system are illustrated. A plastic flowerpot by high-speed injection molding is selected as an example to show the high production efficiency.
