Dramatic reduction in reject rates in polycarbonate lens coating processes thanks to microcleaning with Openair® Plasma

The use of Openair® Plasma rotary jets enables efficient and gentle microcleaning of polycarbonate headlight covers prior to coating them with polysiloxane finishes.

Plasma cleaning removes particles (dust, pigments, etc.) still adhering to the surface after the injection molding process. At the same time, it ensures that the lens is electrostatically discharged. Anti-static blowers are no longer required.

The specific and uniform surface tension achieved results in optimal distribution and uniform thickness of the subsequently applied coating layer. Openair® Plasma thus significantly decreases reject rates.

Quality assurance with Openair® plasma

In 1995, Openair® plasma technology was used for the first time in standard production of automobile headlamp housings in Germany. Today, it has become an established part of applications around the world. At HELLA, Australia, the high process safety of the plasma process is especially valued.
