1. First of all, we first check whether the pressure of the sealing cylinder of the bottle blowing machine is large enough. If it is a low-pressure sealing cylinder, the pressure can be kept below 8 kg, so that there is no problem in blowing ordinary water bottles. But it also depends on the high pressure. If the high pressure is too high and the clamping pressure is too small, the mold will be opened and the seal will leak, which can increase the automatic clamping pressure.
2. Check whether the cylinder block of the sealing cylinder has been damaged.
3. If the sealant is damaged or deviates from the seal, it will leak air.
4. If the threaded mouth of the preform does not match the mouth of the bottle die, it will cause air leakage.
5. Check whether the sealing ring is damaged or missing, or the joint between the coil and the solenoid valve is leaking.
