1. The high-pressure blowing time is too short
The blowing time set in the high-pressure blowing process is too short, which causes the bottom of the bottle to not be blown and the blowing stops, causing deformation of the bottom of the bottle or accumulation of material at the bottom.
Solution: Extend high-pressure blowing time
2. The stretch rod is too short
This problem is relatively rare. Generally, the equipment quality is checked before leaving the factory. Each manufacturer has its own standards, and it is not excluded that small manufacturers are not responsible.
Solution: replace the stretch rod
3. The bottom mold and the mold are not aligned
When the bottom mold is attached, the bottom mold and the closing mold are directly inaccurately connected or misaligned. It may also cause deformation of the bottom or accumulation of the bottom of the bottle.
Solution: adjust the bottom of the mold and the closing position of the mold to ensure that there is no deviation in docking
