Useful length from 1000mm to 6000mm.

Thickness from 2 up to 100mm.

With our four rolls plate bending machine,plate can be bent on both side without return.

Full automatic controlled by PLC,there's no need for additional processing steps for bending the ends.

The flat edge is 1.5-2 times of the thickness.

Quality certificate such as CE and ISO9001.

Accurate, ease of operate, fastest roll bendings

Flat zone of the sheet edges is minimised

Pre-bending, conical bending and ellipse bending can be done easily

Double pre-bends(both ends) in one pass

Hydraulic and electrical system have been safeguarded from overloads and require minimum maintenance

Hydraulic and electrical components are modular and designed according to world standards

The sheet is controlled by tighteding of top and bottom rolls

Most suitable bending operation for CNC applications

More efficient for cycle times

User friendly operations without dependence to operator competence

Feeding on the order sheet to be completed by the prebend Circle, the smaller circular process

Volume in to the curved, cylindrical, conical workpiece

Driving for mechanical transmission, hydraulic transmission for the two movements under the roller
