As the era of high technology has arrived, with the development of industrial technology, our technology can be described as getting better and better, making achievements in the industry, injection molding copper-based products are one of them, then injection molding There are several methods of temperature control.
Barrel temperature: The temperature that needs to be controlled during the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The first two temperatures mainly affect the plasticization and activity of plastics, and then one temperature mainly affects the activity and cooling of plastics. Each plastic has a different activity temperature. For the same plastic, due to different sources or brands, its activity temperature and synthesis temperature are different. This is due to the difference in average molecular weight and molecular weight distribution. Plastics are injected in different types. The plasticizing process in the machine is also different, so the temperature of the selected barrel is also different

Nozzle temperature: The nozzle temperature is usually slightly lower than the maximum temperature of the barrel. This is to prevent the "salvation phenomenon" of the molten material in the straight-through nozzle. The temperature of the nozzle should not be too low, otherwise it will constitute the early setting of the melt and block the nozzle, or the performance of the product will be affected because the early setting material is injected into the mold cavity.

The above is that there are several methods for temperature control of injection molding. It has two kinds of temperatures, each of which is different. From the above text, we can understand that so many kinds of temperatures are used. Only so many products can be made.
