Hella Australia Pty Ltd specializes in automotive lighting equipment and accessories for the most sophisticated new cars in the world. When they needed to improve silicone adhesive adhesion for a Toyota Camry headlamp assembly they found an atmospheric plasma treatment system solved the problem.

The challenge was to improve adhesion on a glue track for a polypropylene headlamp. High temperature from the headlamp caused the silicone adhesive to fail in securing a polycarbonate lens. The Hella team integrated a blown-ion plasma treatment discharge head into a Motoman 6-axis articulating robotic arm. The robotic arm follows the glue track at the precise speed and air gap required to optimize treatment.

The use of the blown-ion plasma treatment has been a success. Hella has invested in multiple systems and their efforts have been recognized by Toyota as they recently won Toyota Australia’s Excellence Award for Engineering.
