This kind of pressure transformation is actually normal. Don’t worry, it’s just that you adjust the pressure in the wrong way.
First of all, it depends on the time you adjust and maintain the pressure. I don’t know how big your press brake machine is or how much you should maintain the pressure, but it can be divided into three points.
When maintaining pressure, you must maintain pressure when there are bent objects, not when there is no load.
The pressure holding time must be enough. Don’t decompress before the pointer is in place.
Do not exceed the rated pressure. In this way, if the pressure you adjust exceeds again, there will be a mechanical problem. If it cannot be reached, it is normal, because some things can be bent in place without so much force, but small things will still reach the adjusted pressure under the condition of maintaining pressure.
