Temperature control occupies a very important part of the injection molding process, which can determine whether the product is good or bad. Guangzhou OTEM Engineering Plastics Co., Ltd. has a professional injection mold processing technology to serve you.

1, cylinder temperature: the whole process of injection of rubber and plastic products need to control the temperature of the cylinder temperature, nozzle temperature and abrasive temperature. The first two temperatures directly affect the melting and flow of plastics, and then a temperature is usually hazardous to plastic flow and cooling. Each kind of plastic has a different flow temperature, the same kind of plastic, because the origin or model is not the same, its flow temperature and dissolution temperature is different, this is because the average molecular weight and molecular weight distribution is not the same, the melting process of plastic in different kinds of injection molding machine is not the same, so the selection of cylinder temperature is also different.

2, nozzle temperature: the nozzle temperature is generally slightly lower than the end temperature of the barrel, which is to prevent the "flow water condition" that may occur in the directly connected nozzle. The nozzle temperature can not be too low, otherwise it will lead to the early solidification of the molten material and the nozzle is blocked, or because the early solidification is introduced into the mold core, which affects the performance of the product 3, abrasive temperature: abrasive temperature affects the most essential performance and apparent quality of the product. The abrasive temperature depends on the availability of plastic crystal shape, product size and structure, performance regulations, and other process parameters (melt temperature, injection speed and injection pressure, rubber and plastic product cycle time, etc.).
