What should I do if the hydraulic bender is out of sync?

Is there any way to overcome this? Through inspection and analysis can be determined, causing the hydraulic bending machine falling out of sync is the problem of the piston cylinder, mainly because of its internal leakage phenomenon, and about two cylinder leakage amount is not exactly the same, this will make the two cylinder running out of sync.However, because the hydraulic bending machine's return travel speed is much higher than the bending speed, it will cause the phenomenon of equipment falling out of sync, which will seriously affect the product bending quality.Hydraulic bending performance is enough to the material bending, while the efficiency is often done, so more and more users are favored.  In order to make the leakage amount in two cylinders equal, on the one hand, try to make the matching precision of related parts consistent, on the other hand, try to make the hydraulic circuit design of two hydraulic cylinders the same.In this case, hydraulic bending machine falling out of sync situation is possible to avoid.That is to say, if we can control the hydraulic cylinder of the bending machine leakage, make it consistent can solve the problem.
