SCREW CLEANING DURING EXTRUSION WITH CLEANING AGENT – FC

The cleaning agent is ready for direct use. Before starting the cleaning procedure, make sure that the screw is filled with the regular material.
During the entire cleaning procedure, the screw must remain continuously filled.

Step 1 – Switch off the venting (degassing) and remove the filter (removing the filter is not mandatory and serves as a precautionary measure to prevent clogging).

Step 2 – Keep the screw temperatures unchanged.

Step 3 – Add the cleaning material into the hopper.
If there are difficulties with feeding the cleaning material:
3.1 Increase the screw speed.
3.2 Add the cleaning agent more slowly.
3.3 Feed the cleaning material in small portions, alternating with the regular material (e.g. 2 kg cleaning agent – 1 kg natural – 2 kg cleaning agent, etc.).

Step 4 – Reinstall the filter, switch the venting back on, and start production.
