What is a plastic injection mold ?


   The molds and products we use in our daily production and life range from the base of the machine tool to the outer casing of the machine. It is small enough to have an embryo screw, a button and a shell of various household appliances, all of which have a close relationship with the mold. The shape of the mold determines the shape of these products, and the quality and precision of the mold determines the quality of these products. Because of the different materials, appearance, specifications and uses of various products, the mold is divided into casting molds, forging dies, die-casting dies, stamping dies and other non-plastic molds, as well as plastic molds.


  In recent years, with the rapid development of the plastics industry and the continuous improvement of the strength and precision of general and engineering plastics, the application range of plastic products is also expanding, such as: household appliances, instrumentation, construction equipment, automotive industry, In many fields such as daily hardware, the proportion of plastic products is increasing rapidly. A well-designed plastic part can often replace multiple traditional metal parts. The trend of plasticization of industrial products and daily-use products is on the rise.


   Injection Mold: Injection 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. The injection molding process is the best choice for efficient and mass production of precision and appearance parts for plastic parts.
