Recycled Plastic Material PP PE Film Granulator Double Two Stage Pelletizing Line Machine

Heating and cooling device

Heating and cooling are essential for the plastic extrusion process.

(1) Nowadays, extruders usually use electric heating, which is divided into resistance heating and induction heating. The heating sheets are installed in the fuselage, neck and machine parts. The heating device heats the plastic in the cylinder from the outside to raise the temperature to achieve the temperature required for the process operation.

(2) The cooling device is set to ensure that the plastic is within the temperature range required by the process. Specifically, it is to eliminate the excess heat generated by the shear friction of the screw rotation, so as to avoid the temperature being too high, so that the plastic is decomposed, scorched or shaped. The barrel cooling is divided into two types: water cooling and air cooling. Generally, small and medium-sized extruders are suitable for air cooling, while large ones are mostly water-cooled or combined with two forms of cooling. The screw cooling mainly uses central water cooling to increase the material solids conveying rate. Stabilize the amount of glue and improve the quality of the product; however, the cooling at the hopper is to strengthen the conveying effect on the solid material, prevent the plastic particles from sticking and blocking the material due to the temperature rise, and the second is to ensure the normal operation of the transmission part.
