Injection molds must consider these three processing technologies

Injection molds must consider these three processing technologies

(Summary description)In the processing of injection molds, this complete professional technology is an indispensable project. It involves transforming plastics into products that retain the original system performance. The important production process design conditions of injection molding are the temperature, pressure and the corresponding different effects that affect the plasticizing flow and cooling. Here, our general analysis can be divided into three aspects: one, temperature and control, two pressure management control, and three molding cycle. There are a total of 3 points for temperature control to indicate the working temperature of the barrel, nozzle, and mold as follows:

1. Barrel temperature: According to different conditions, the temperature of the selected barrel is also different. The temperature to be controlled in the injection mold process is the cylinder temperature, which mainly affects the plasticization and flow of the plastic. Each plastic has a different flow temperature. The same plastic has different flow temperature and decomposition temperature due to different sources or brands. This is due to the difference in average molecular weight and molecular weight distribution. Plastics are also different in the plasticization process of different types of injection machines. , So the choice of barrel temperature is different.

2. Nozzle temperature: Normally, the nozzle temperature is slightly lower than the ambient temperature of the barrel in this case. This is to prevent the occurrence of drooling when the melt is in the straight-through nozzle. The temperature of the nozzle should not be too low, otherwise we will block the nozzle due to the early solidification of the melt, or the performance of the product will be affected by the early solidification of the material injected into the cavity, and proper temperature control can guarantee the product’s performance. Performance and other characteristics.

3. Mold temperature: Generally speaking, mold temperature has a great influence on the internal performance and appearance quality of the product, and it can be said to be a very important factor. The temperature of the mold depends on the crystallinity of the plastic, the size and structure of the product, the performance requirements, the melt temperature, the injection speed, the injection pressure and the molding cycle.
