Pneumatic press design principle is to do the cylinder linear motion of the cylinder piston rod to do linear motion back and forth, back and forth punch on the material pressure, make its plastic deformation, and get the required shape and precision, so you must cooperate with a set of mould (upper die and lower die), the material placed in the meantime, the pressure on the machine, make its deformation, when processing applied to materials caused by the force of reaction, the punch machine absorbed by the body.
