What ‘s the differences between hydraulic punching and pneumatic punching during the roll forming process?
Hydraulic presses and pneumatic presses can provide many of the same functions with equal quality. They can both be adjusted to changed the stroke length or the stroke pressure. They both have full tonnage and any position along their stroke, making them preferable to mechanical presses. They can both perform complicated pressing and forming tasks with the proper modification as you go along.
The main difference between them is their speed. Pneumatic presses are much faster than hydraulic presses, and that means their are many jobs they can perform faster and more efficiently. However, this makes them ill-suited for hydroforming or other jobs where the hydraulic press’ slower speed is an advantage.
There are also differences as far as maintenance. Hydraulic presses require more care, and have more components attached to them for this purpose, making them more complicated. Pneumatic presses require less time and energy for maintenance.
