The use of plasma jets on industrial robots allows highly precise, rapid and environmentally responsible surface 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.
Unlike the commonly used flame method, surface 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.
