How Can We Adjust The Temperature Of Granulator?
Plastic extrusion machine as a key industrial production technology, it will transform plastics into effective and can maintain the original performance of the product, in order to better maintain the excellent application of machinery and equipment filling, its adjustment has a very great effect, today, I will take you to master its temperature regulation how to do.
The key of temperature control of the machine equipment is to operate the cylinder, nozzle and mold shell from three levels.
1. Cylinder temperature
The temperature of the whole process of injection of rubber and plastic products needs to be controlled, such as the temperature of the flavor cylinder, the nozzle temperature and the mold temperature. The first two temperatures are critical to the melting and fluidity of plastics, and then one temperature is mainly harmful to the fluidity and refrigeration of plastics.
Each kind of plastic has a different flow temperature, the same kind of plastic, because the source or model is not the same, its flow temperature and dissolution temperature are different, it is because the average molecular weight and content are not the same, the melting process of plastic in different kinds of injection molding machine is not the same, so the temperature of the selection cylinder is not the same.

Two, nozzle temperature
The nozzle temperature is generally slightly lower than the barrel temperature, which is to better avoid the "flow water condition" that the molten material is likely to produce in the directly connected nozzle. The nozzle temperature can not be too low, otherwise it may lead to the early solidification of the melt and plug the nozzle, or because the early solidification is introduced into the mold core and harm the performance of the product.
Three, mold shell temperature
Mold temperature is very harmful to the intrinsic properties and conductivity quality of the product. The height of the mold temperature is determined by the plastic crystal shape, product specifications and structure, performance regulations, and other melting temperature, injection rate and injection working pressure, rubber and plastic products cycle time and other processing standards.
