As China's largest automotive supplier, YF is specialized in the manufacturing of dashboards for cars and uses Jenoptik laser systems to create so-called predetermined breaking points for airbags. Since 2002, YF had already purchased several large laser systems of the JENOPTIK-VOTAN® A series from Jenoptik. At the end of 2013, Jenoptik delivered the worldwide 200th laser system of this type to the Chinese partner.
With these laser systems so-called predetermined breaking points are created by laser perforation in airbag flaps. On the back of the material the laser generates a tear line along the desired shape of the airbag flap. A specially developed sensor system prevents the laser from completely severing the material. However, the perforation line weakens the material in a way that allows the airbag to break through this line and open up during a collision.
Patented laser perforation process.
The JENOPTIK-VOTAN® A laser perforating system is suitable for the manufacture of concealed predetermined breaking points for passenger and knee airbags in car dashboards. The system is capable of processing single or multi-layer materials and decorative layers made from plastic, textiles or leather, working quickly and reliably. Customer-specific solutions allow for flexible processing of airbag covers: the type of perforation holes, their spacing and the shape of the perforated line are variable and can be adjusted according to the type of material being used.
