Machinery and Plants

To generate the orbital motion, dyconn machines use eccentric shafts that are driven by a servomotor. The engine speed determines the maximum frequency of the orbital motion and the eccentricity determines the maximal amplitude. The speed can be selected randomly via the servomotor.

Several eccentric or orbital shafts drive the so-called orbital plate to which the component is attached. The motion of the orbital plate will be purely translational if several eccentric shafts are combined. In order to absorb the necessary axial forces of the reaming and upsetting process the orbital plates are supported hydrostatically or by means of a thrust roller bearing.
Two opposing orbital plates are used in the case of multiorbital friction welding machines. Each plate is driven by a servomotor synchronized by the machine controller. This permits a torque-synchronous movement of both motors. In this case, relative speed can be influenced by the speed of the orbital motor and the angle difference between the two motors.
The speed, and thus the heat input, are greatest when both components move at an offset angle of 180° relative to one another. If the offset angle is 0°, the components no longer move on each other.
As synchronization is mainly carried out with the help of the software, one motor can be switched off without any problems, resulting in a single orbital movement.
The operation in opposite directions of the two orbital drives results in a (multi-) linear relative motion of the joining parts towards each other. This allows the user to weld together even thin metal sheets.
The operator of a multi-orbital friction welding machine can choose between these three modes by pushing a button.

Process Monitoring

The monitoring of all important process parameters of our machines ensures the high repeatability and quality of the welds. The path is monitored using a highly precise linear glass scale. The installed load cell provides the values for force control.  The component is controlled via a high-performance control system.



This system solution is optimised for the series production of plastics and relies on a thrust ball bearing. This bearing makes it possible to achieve a cross section of up to 50,000 mm² for plastics and up to 400 mm² for light metals. Our customers appreciate the relatively low floor space required. The modular control supports the full scope of possibilities of multi-orbital technology. 


With a hydrostatic thrust bearing, this model has proven itself in series production applications for metals such as titanium and steels with a cross section up to 600 mm². Ease of maintenance and the stiff hydrostatic bearing of both orbital plates are among the reason why our customers like to use this machine.

dyconn-200H single

Single means single orbital. Our dyconn-200H single drives one orbital head which allows to weld small parts to a very big one. It carries on its 3 axis machine table up to 1 ton load. This machine produces from many components in short cycles a precise and complex part. The maximum welding cross section can be up to 875 mm² with S235JR and up to approximately 2.300 mm² with titanium alloys.

dyconn-250 polish

The orbital motion used for polishing. The vertical and robust construction of the dyconn-250 polish makes it best for finishing two mould halves at once.
