1. Sealing cylinder pressure enough, if the selection of low pressure sealing cylinder, low pressure can be maintained below 8 kg, the general water bottle is no problem. But it also depends on the high-pressure blowing pressure. If the high-pressure blowing pressure is too high, the sealing cylinder will be pressed down. If the high-pressure pressure is reduced, the bottle shape can be blown. Try to reduce the high-pressure pressure pressure, or if the high-pressure pressure pressure is too high and the clamping pressure is too low, the mold will be opened, which will also lead to sealing leakage. The automatic clamping pressure can be increased.

2. Whether the sealing glue is damaged or aligned with the sealing place. If it deviates from the sealing place, it will leak.

3. Seal cylinder block or seal damage, if the seal damage can be directly reflected, open the seal cylinder solenoid valve to know.

4. Whether the solenoid valve of sealing cylinder is leaking or stuck or the exhaust is not smooth, these are also the reasons for the leakage of sealing cylinder.
