Laser welding is used to combine two plastic parts as efficiently and qualitatively as possible. One of the two components is laser-transparent and the other laser-absorbing.

Hans von der Heyde develops the right machine concept for every application from a modular system depending on individual requirements such as degree of automation, cycle time or component geometry. We work with component-specific changing devices, so that different items can be produced with one system – with no major set-up effort.

In addition, the integration of the laser welding process into a comprehensive task is possible, for example as a station within an assembly rotary table. We select the appropriate welding process for each application and develop the laser components.

Contour welding


In this welding process, the laser beam passes through the geometry to be welded exactly once. This is done either by moving the laser beam or the component itself with a robot, a linear or rotary axis.

Quasi-simultaneous welding


In quasi-simultaneous welding, the laser beam moves very quickly several times over the geometry to be welded. In this way, the necessary energy is generated quasi simultaneously over the entire surface. The movement of the beam is generated by the scanner in the laser module.
