Dramatic reduction in reject rates in polycarbonate lens coating processes thanks to microcleaning with Openair® Plasma
use of Openair® Plasma rotary jets enables efficient and gentle
microcleaning of polycarbonate headlight covers prior to coating them
with polysiloxane finishes.
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
specific and uniform surface tension achieved results in optimal
distribution and uniform thickness of the subsequently applied
Openair® Plasma thus significantly decreases reject rates.
Hella Australia Pty Ltd.
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.
