Clamping force can be evenly applied to all over the die plate
The die is stabley absorbed all over the face by the magnetic force and there is no force dispersion
when clamping the die. It can restrain the gap between the machine and the die also enables thequality of the parts to improve.

Suitable for the machine which cannot secure the space for a hydraulic clamp
The press mag clamp absorbes and ﬁxes the mold by the magnetic force generated from the plate and there isno space required for mounting the clamp and therefore the slide or bolster surface can be used to themaximum. Also there is no need to standardize the mold size and no need for T-slots on the machine nor U-cuts
for the die.

Air-driven, Compact, High performance hydraulic pumpHigh cycle, reliable reciprocation of air and hydraulic piston ensures a repetitive suction and discharge oil process. As dischargepressure hikes up to the circuit set pressure, reciprocation goes slow eventually. Pascal pump stops at the time the dischargepressure reaches the set pressure then keeps balancing air and oil discharge pressure. At the balanced condition, Pascal pumpnever consumes air and there is no power loss or oil temperature rise unlike an ordinary electric motor pump.
In the event of pressure drop (oil leakage) in the circuit, the pump immediately reacts to start pumping for recovering the pressure
loss. When leaking oil, the pump restarts pumping and the sound of pumping is like an alarm for leakage to call operator forservicing.
