Heating and cooling device for laboratory extruder:

The extruder is usually divided into electric heating, resistance heating and induction heating, heating installed in the fuselage, neck, head of each part. The heating device is made up of the plastic in the external heating cylinder so as to increase the temperature required for the operation.

The cooling device is to ensure that the plastic in the temperature range of the process requirements and settings. In order to avoid the excess heat generated by the shear friction of the screw rotation, in order to avoid the high temperature, the plastic decomposition, scorch or stereotypes are difficult. Cylinder cooling water cooling and air cooling is divided into two kinds, small and medium sized extrusion machine adopts air cooling is more appropriate, large use more water or two kinds of combined cooling; cooling water cooling screw mainly adopts the center, the purpose is to increase the solids conveying rate, stable glue volume, and improve product quality; but in the cooling hopper one is, in order to strengthen transport of solid material, prevent warming plastic sticky jam outlet, two is to ensure the normal work of the transmission part.
