Reliable, efficient pretreatment of large or intricate car interior parts with Openair® Plasma

The use of plasma jets on industrial robots allows highly precise, rapid and environmentally responsible pretreatment of large three-dimensional car interior parts prior to coating, wrapping, in-mold decoration or in-mold labeling. For pretreatment of parts like instrument panels, door trims or sidewall trims a number of wide-angle rotary plasma jets are used, making it possible to achieve rapid uniform surface activation even over large areas.

Complex components such as automobile instrument panels are treated inline with a robotic Openair® plasma system. The plasma treatment can be adjusted to sweep large areas or to precisely follow contours where adhesive is to be applied.

Unlike the commonly used flame method, pretreatment with Openair® Plasma causes only minimal heating of the parts. There are no undesirable side-effects such as deformation or too intensive treatment which would lead to a loss of adhesion.

Advantages of surface activation with Openair® Plasma:

High, uniform quality of activation even on large surfaces
Permits the use of non-polar recycled materials
Reliable process technology
No chemical consumables
No thermal distortion or degradation of parts

Plasma Instead of Flame

Peguform pretreats the instrument panels for Audi Q5 off-road vehicles with Openair® plasma instead of the usual flame processing. The selectively applied “cold” plasma jet eliminates the need for masking, while simultaneously protecting the plastic from overheating
