Cooling process of blow molding machine and matters needing attention

Cooling plays an important role in the production and processing process of blow molding machine. The cooling effect directly affects the quality of blow molding products. Therefore, MEPER MACHINE today to share with you is blowing molding machine cooling process.


The cooling process of blow molding machine mainly includes screw cooling of blow molding machine, body cooling of blow molding machine and cooling of blow molding products. Today I want to share with you the cooling of blow molding machine screw and blow molding machine body.

Cooling of blow molding machine screw

The purpose of screw cooling blow molding machine is to alleviate the friction overheating situation, so that the pressure of plastic embryo extrusion blow molding machine is more stable, so as to ensure that the plastic raw materials can be fully mixed and stirred evenly, to ensure the plasticizing quality of plastic raw materials, improve the quality of blow molding products.


However, in the process of blowing machine screw cooling, we should pay attention to the reasonable control of blowing machine screw cooling time and temperature, do not over cooling. A certain buffering process should be left before cooling. If the molten plastic in the cylinder suddenly cools, a very serious accident will occur. Moreover, if the cooling of the blow molding machine screw is used before extrusion, it will also cause serious accidents.


Cooling of blow molding machine body

The purpose of blowing machine body cooling is to speed up the barrel heat dissipation, so as to avoid the temperature rise caused by friction overheating.

Why avoid such an increase in temperature? So here's a little bit of popularization.


The temperature rise caused by friction overheating will not stop immediately during the plastic extrusion process, even after cutting off the heating power. Therefore, it is necessary to cool this process to speed up the heat dissipation of the barrel, so that the barrel can be cooled down in a certain period of time, while maintaining the heat balance in the extrusion process.


Blow molding machine body of the cooling process, we should pay attention to is that cooling blow molding machine and blow molding machine heating temperature Settings, is the need for segments, although mainly fan cooling, but the functions of the blow molding machine paragraphs fuselage is different, so we need different cooling set, can do even effective cooling.


The cooling process of blow molding machine is shared here today. The next article will share the cooling of blow molding products. Please continue to pay attention to us.
