4 rolls plate bending machine

Dea 4R

The DEA 4R hydraulic Plate Bending Machine is an extremely robust machine, characterized by the movement of the side rollers on straight guides.

Thanks to its structure and the high precision of the movements given by the technologically updated electronics, accuracy is ensured in the invitation and bending phases. All the operations of the machine are controlled by a state-of-the-art PLC and upon request it is An easy-to-use CNC control is also available. The ideal machine for mass production.

Advantages
