Symptom on the extruder
Profiles with incomplete fusion, uneven gloss or a narrow thermal window rarely fix by “raising temperature” alone. Processing aid, lubrication and stabilization must be read together.
Reading order
Start from part type (profile, pipe, injection). Confirm delayed fusion, plate-out and unbalanced internal/external lubrication before swapping the aid blindly.
Next step
Extrusion, injection and PVC profile landings point to the SKU. Request a processing-aid sample and align the lubrication package with Plectus engineering.
