What is the reason for the temperature of the twin screw extruder, which is 200 degrees down to 150 degrees, and the temperature can not rise?

Feb 26, 2018

In the process of extrusion, the temperature of the cylinder drops obviously, and the main reasons are as follows:

1 the cooling water is not properly controlled, the flow of cooling water is too large or the temperature is too low.

Damage of 2 machine barrel with part heater

The power of the heating ring used in the 3 machine barrel is too small

The following measures are as follows:

1 check whether the cooling water solenoid valve is damaged or whether the water temperature is suitable

2 the heater has no current when it is electrified, and it detects whether the heater is damaged or not.

3 check the power of the heater
