What to do when the extrusion temperature is unstably in production?
When the users operate the Plastic extrusion machine, sometimes they may get the problem of unstably extrusion temperature in production, The temperature of each section of the barrel fluctuates greatly and cannot be maintained at the set value, affecting the plasticization effect of the material, and failed production or unqualited products are made.
Sure engineer suggest users to check below possible causes and related handling method when the plastic extrusion temperature is not stably
| Possible causes | Handling method |
|
Fault of the heating device (damage to the heating rod or heating coil) |
Check the heating element, replace the damaged heating rod or heating coil, or change the heating elements |
|
failure of the temperature control instrument |
calibrate or replace the temperature control instrument |
|
damage to the thermocouple or poor contact |
reconnect or replace the thermocouple |
|
unstable friction heat generation caused by fluctuations in the screw speed |
check the transmission system to ensure the stability of the screw speed. |
