HEAVY DUTY mandrel bending machines for the production of small series and single bends

The semi-automatic mandrel bending machines from the HEAVY DUTY range offer an economically interesting alternative to our CNC machines. For example, they are perfect for manufacturing single bends and smaller series for use in shipbuilding, the offshore industry and plant construction. They are cost-effective without compromising on quality or performance. Equipped with special tools, these machines can be used to bend both thin-walled and thick-walled tubes to meet your requirements. The machines are controlled easily and intuitively via a touch screen so bend angle corrections can be implemented directly.

A strong basis

Like our fully automatic CNC machines, our semi-automatic HEAVY DUTY range is based on extremely stable basic machines with a very high level of rigidity. This enables them to withstand maximum bending forces and ensures sufficient reserves. You can therefore be sure of sustainable reliability and first-class bending results.

HEAVY DUTY – robust tube bending machines for plant construction, shipbuilding and the offshore industry

Our HEAVY DUTY machines are designed for continuous use in tough conditions. Their particularly high rigidity prevents the machine body from twisting at high clamping forces which results in high-quality bending results even in fast production cycles. Whether you are producing complex geometries or different bending radii, our HEAVY DUTY machines ensure maximum precision at high forces – all in a user-friendly package.

Please feel free to contact us for advice about the right machine for your needs.
