In order to deliver the best blow molding
performance, it is customary within the
conversion industry to establish ‘recipe’ guidelines
per resin/per supplier as different PET resin
production technologies and different specific
resin formulations can significantly influence
the blow molding performance.

Set up conditions
Configuration
- When starting to process a new resin, first
run through new preforms for 15 minutes at
‘standard’ conditions to establish steady state
conditions prior to any process optimization
- Slowly start to reduce preform blowing
temperatures until failures are present
(visible pearl internal wall or pearl feet)
- Increase blowing temperatures until defects
are eliminated
- QC check bottle quality for acceptance versus
established tolerances
- Change the power consumption profile in the
ovens for early heat and longer sink times but
ensure overall temperatures do not exceed cold
crystallization temperature
- Repeat temperature reduction stage and
then defect elimination stage to test if further
optimization is possible
- Recheck QC bottle quality for acceptance versus
established tolerances
- Log all process parameters and create new
specific ‘recipe’ for future use
