PET Preform Injection Moulding

Titanium oxide-based colourants

Attention: If you work with titanium oxide-based colourants, preforms can look clean under natural light but show “ghost marks” under direct bright light. We have determined this contamination comes from the screw. For this specific case, we recommend running a Screw only cleaning routine.

If this is not the case, jump to Step 43 to finish the purging process.
