Injection molding process of injection mold

- Nov 10, 2016-

     The injection molding process of injection mold can be roughly divided into three steps, first, the temperature control; Second, the pressure control; Third, the molding cycle.
Temperature control is divided into material barrel temperature control, nozzle temperature, mold temperature control. The flow of different plastics have different temperature, so good to select each of the plastic cylinder temperature. Nozzle temperature is usually below the cylinder temperature, nozzle temperature affect after molding, products performance. And mold temperature on product performance and quality also has a great influence, mold temperature control situation according to the size and structure of the crystalline, mold and other external and internal conditions.
Plasticizing pressure and injection pressure control is divided into two large pieces. Plasticizing pressure requirements of the technical level is higher, it should be according to the quality of the injection mould and plastic kind of constantly changing, and the injection pressure is to the flow resistance of cylinder, giving the mold filling rate and liquid by powerful help
A complete injection process is molding cycle. Molding cycle can affect the utilization of labor and equipment utilization rate, so try to shorten the molding cycle time, has been to maximize efficiency. Injection time and cooling time have a crucial impact on the quality of the products, so we're going to on the quality of injection mold at the same time, shorten the cycle.
