Everyone will not be unfamiliar with the raw material of plastic. It is a common raw material in many products in our daily life. Because of its strong plasticity, hardness and density, it can be used in industrial production in addition to being made into small tools in life. So which one of the Shenzhen injection molding factories we can see on the market is strong?

One of the processes commonly used in Shenzhen injection molding plants includes injection molding. And injection molding is a processing method that can be used to mass produce certain parts with complex shapes. The process refers to injecting the heated melted material into the mold cavity by high pressure, and after cooling and solidifying, we can obtain the molded product. In its process, the control of temperature is more important. For example, the temperature control of the barrel. The temperature that we need to control in the injection molding process includes the barrel temperature, nozzle temperature and mold temperature. The first two temperatures mainly affect the plasticization and flow of the plastic, and the latter temperature mainly affects the flow and cooling of the plastic. Plastics have different flow temperatures. Due to different sources or grades, the flow temperature and decomposition temperature of the same plastic are also different. This is due to the difference in molecular weight and molecular weight distribution. Plastics are used in different types of injection machines. The plasticizing process is also different, so the barrel temperature is also different. In addition, we need to grasp the nozzle temperature. The nozzle temperature is slightly lower than the high temperature of the barrel. This is set to prevent the salivation of the melt in the straight-through nozzle. The temperature of the nozzle should not be too low, otherwise it will cause the premature solidification of the melt and block the nozzle, or the performance of the product will be affected due to the premature solidification of the material injected into the cavity. In addition, we also need to control the temperature of the mold, which has a great impact on the internal performance and apparent quality of the product.

The injection molding plant is our place for the production and processing of plastic products. The completeness of the equipment and the operation level of the operators on the production line are important factors that affect the quality of the products. Therefore, when choosing a cooperative factory, the company should choose a Shenzhen injection molding factory with a good reputation in the industry and a high level of business for cooperation.
