Something You Have to Know about the Technical Term of Plastic Mold

    In recent years, with the rapid development of plastic industry and general engineering plastics and strength and precision in areas such as continuous improvement, the scope of application of plastic products is also expanding, such as: household appliances, instrumentation, construction equipment, automobile industry, With hardware and other fields, the proportion of plastic products is rapidly increasing. A well-designed plastic part can often replace a number of traditional metal parts. Industrial products and household products, the trend of plastic is rising. 

    The general definition of mold: In industrial production, with a variety of presses and special equipment installed on the press, through the pressure of the metal or non-metallic materials to produce the desired shape of the parts or products, such special tools collectively referred to as mold .

    Injection molding process description: mold is a tool for the production of plastic products. It consists of several sets of part parts, this combination has a molding cavity. Injection molding, the mold clamping in the injection molding machine, the molten plastic is injected into the molding cavity, and cooling in the cavity stereotypes, and then separate the upper and lower mold, the top of the system from the top of the mold cavity from the mold, the last mold closed For the next injection, the entire injection process is cycled.
