A mold is a tool for producing plastic products. It consists of several sets of parts with a molded cavity. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and is cooled and shaped in the cavity, and then the upper and lower molds are separated, and the product is ejected from the cavity from the cavity through the ejection system, and finally the mold is closed. For the next injection, the entire injection molding process is cyclic.
Injection molding is the most commonly used method in plastic processing. The method is applicable to all thermoplastics and some thermosetting plastics. The amount of plastic products produced is far beyond the reach of other molding methods. As one of the main tools for injection molding processing, the injection mold is in the quality precision, manufacturing cycle and injection molding process. The level of production efficiency and other aspects directly affects the quality, output, cost and product renewal of the product, and also determines the ability and speed of the company's response in the market competition.
