The type UMR tube forming machines use smart operating technology with many predefined settings that can be retrieved automatically to achieve perfect mirror-like surfaces. When producing flares with 20°-90° angles, with a clamping length of 1 x D, the machine achieves perfect sealing surfaces. Flaring up to 90° can be produced in a single cycle. Tools can be changed extremely quickly. With the appropriate tools, the machine can also close tube ends.

Our rotational technology increases the possibilities of forming on tubes with minimal expenditure on tools. All the drives are servo-electric by design and, if needed, CNC-operated. In our SRM rollforming machines, all the settings are preloaded, so there is no longer any need for costly adjustments. Different tool variants further expand the processing possibilities for chipless cutting or post-bending cutting. The machines can produce internal and external profiles and can also roll in synchronicity thanks to a special tool head (inside/outside).

With the new generation of our combination machines, we have continued to develop the new diversity for forming pipes. Geometries that effectively replace high-cost and expensive turned parts can be formed directly at the pipe end in the endforming machine – for a final component of a single workpiece that is ready for use without elaborate soldering or welding. Implementation of the combination can be specified by you or based directly on the forming geometry. This is usually done using up to 6 axial forming stages and at least one rotary unit. Trimming, as well as axial and rotary forming, may require 2 rotary forming stations. Simple trimming or deburring after forming at the pipe end are no demanding challenges. Therefore, all our axial forming machines and combination machines are equipped with one or several single-drive axes. They have a servo-electrical drive and can be used in each of the holders for the forming stages, making the system is very flexible and compact.
