Plastic welding Mechatronics

Actually only advantages

Laser welding of plastics has been an integral part of production in the automotive industry for more than 20 years. In addition to flexibility, the industry appreciates that plastic welding has the following properties. It is

  • fast
  • neat
  • process-safe
  • economical
Plastic welding with laser in automotive engineering

Application example - Cover welding gear unit

The PA6 GF30 natural/black assembly shown in the picture on the right is joined by quasi-simultaneous welding. The laser welding process must be as economical as possible and achieve a category IP6K7 tightness with process reliability.

Due to the flexible production concept of the customer, who works with a belt transfer system, a solution based on our process modules was developed. The EVO 3800 is completely integrated, secures laser class 1 and is equipped with all necessary communication interfaces. The process setup as well as any necessary adjustments are comfortably implemented with the EvoLaP process software.
