Laser cutting tear line and airbag laser drilling

【摘要】

For high performance of passive safety functions – such as passenger airbags, precise tear lines must be implemented in vehicle interior components. Using Jenoptik‘s technology, weakening is accomplished by laser, which allows very sensitive ablation of material from the back of the workpiece. Specific laser radiation sensors enable a closed-loop machining process to produce uniform weakening with minimal residual wall thickness, but prevent the laser from completely cutting the material. As a result, the highest levels of safety and aesthetic requirements can be met, as the weakening line is completely invisible.
