Dear if you have problem for the plastic going inside neck than first you increase parison cut delay small and than decrease parison cut time small than increase pre blow air of parison after this all you short out this problem easily if possible than also decrease speed of hot cutter.
After all if you have problem than please adjust some timer like blow delay increase,blow pin slw dwn delay increase but not more than blow delay it will be less than blow delay.

Hi
I have been constantly having the problem of plastic going inside neck bores and blocking it.
The issue is also closely related with my hot cutter which turns dark and avoids cutting and thus sticks the parison. I have to regularly assign people to file the cutter in order to remove deposits from the cutter. Any other remedies?
Regards
Balal
