1. the pressure of the sealed cylinder is insufficient. if you choose a low-pressure sealed cylinder, the low-pressure pressure can be kept below 8 kg. generally, water bottles are fine. but this also depends on the high-pressure blowing pressure. if the high-pressure blowing pressure is too high, the sealing cylinder will be pushed down. if the high pressure pressure can be reduced, the high pressure pressure can also be blown into the bottle to try to reduce the high pressure pressure, or if the high pressure pressure pressure is too large, the clamping pressure will be reduced. if it is too small, the mold will be opened, which will also cause sealing leakage, and can increase the pressure of automatically clamping the mold.

2. whether the sealant is damaged or in the positive sealing position, if it deviates from the sealing position, it will leak.

3. whether the sealing cylinder or the sealing element is damaged, if the sealing element is damaged, it can be directly reflected by opening the solenoid valve of the sealing cylinder.

4. whether the solenoid valve of the sealing oil cylinder is leaking or stuck or the exhaust is not stable, these are also the reasons that affect the leakage of the sealing oil cylinder.
