1. The heating temperature at the bottom of the bottle is not enough.
The main reason for the accumulation of material at the bottom of the bottle blowing machine is that the heating temperature of the bottom of the bottle does not meet the predetermined requirements, and the bottom of the bottle cannot be blown when blowing. The bottle solution: adjust the temperature of the heating lamp at the bottom of the bottle.
2. Insufficient pre-blowing time.
The pre-blowing time is too short, causing uneven blowing when blowing at the bottom of the bottle, resulting in accumulation of material at the bottom of the bottle.
Solution: Extend the pre-blowing time.
3. The stretch rod is too short.
This kind of problem is relatively rare. Generally speaking, the blow molding machine will undergo a quality test before leaving the factory. Each manufacturer has its own standards, and it is not ruled out that small manufacturers are irresponsible.
