The permanent mold casting process of plastic parts mainly includes four stages: filling, holding pressure, cooling and demoulding, which directly determine the turbocharger compressor housing molding quality of products, and these four stages are a complete and continuous process.

In the complex system of modern manufacturing industry, car roof rack injection tooling occupies an irreplaceable key position, and its importance is reflected in many aspects, which profoundly affects the whole process of product manufacturing and the development of enterprises.

Auto door trim molding technology produces the desired part or product by shaping the molten material into a cavity. The geometry of the cavity outlines the three-dimensional shape of the designed product. High pressure is usually applied during the injection process to promote material flow and maintain density after the material solidifies.

In the design of car head light plastic injection mold, cooling system plays a vital role, and the rationality of its design is directly related to product quality, production efficiency and production cost.
