Our Accomplishments for your Benefit

Patent Pending Heating Device

Unique CNC bending technology for plastic tubes enables aquick adjustment of geometries and a shorter time-to-market
J Complex geometries can be produced by means of an industrial robot supporting the workpieces
J Simple programming via geometry input without separate
programming of robot
J The use of an internal mandrel during the bending process
allows thin wall thicknesses, small bending radii with ahomogeneous cross section and a smooth inner surface ofthe tube wall that reduces pressure drops of the fluids flowing
through the tubes
J Heating device with CNC positioning for material-protecting
heating of all thermoplastics

Heating device with free positioning and infinitely adjustable
heating zone for gentle heating of bent parts by hot air. The
workpiece is partially heated in defined bending areas during thebending process. Heating is controlled thanks to non-contacttemperature monitoring at each bend by means of a pyrometer..

Innovative, Future-Oriented and Flexible –WAFIOS CNC-Plastic Tube Bender

Bending of thermoplastic tubes with revolutionary technology

Unique, versatile and flexible machine concept with trend-setting
production process for bending plastic tubes up to 35 mm
outer diameter. WAFIOS HotBend 35 enables straight plastic
tubes to be bent using the 3D bending process, comparable
to a conventional tube bending machine. In this process, thebending area is heated with hot air in the patent-pending heatingsystem. Next, the rotary-draw bending technique is used tomake the according bends. The proven TWISTER² technology isused to support the tube geometry. During the bending process,the handling robot dynamically supports the plastic tube andstabilizes it during the cooling process. The robot movementsare automatically determined by the WAFIOS WPS 3.2 programming system. Accordingly, even small series can be produced
flexibly and economically.
