We have been blowing 2 oz PET bottles we have random pinhole leaks show up off and on, trying to figure it out.
Items we have tried
Stretch rod tip design
Processing parameters
Machine processing combinations
PET processing combinations - temp control - speed -pressures etc
upon close examination pinhole is in gate area always, sometimes as a minute hole, sometimes of a crack in gate area.
We are catching with leak detection but would prefer not to make them
We are blowing PET with White colorant.
