A Brilliant Finish - A new atmospheric plasma pretreatment technology can improve the finish quality on plastics, metal and glass

摘要

Design elements and immaculate surfaces are assuming an increasingly greater importance in today's highly competitive markets. Whether on automotive components, mobile phone housings, perfume bottles or numerous other products, industry is spending exponentially rising sums to improve the appearance of products through enhanced finishing processes, A decisive factor in finishing is achieving the best possible cleaning and activation of the surfaces to be coated. Pretreatment processes range from ionization or flame treatment to wet chemical processes, power washing, the use of primers and even mechanical cleaning with ostrich feathers. Despite all the efforts being made, the proportion of rejected parts in production caused by problems such as painting over dust particles is often well above 10%. Additionally, conventional pretreatment methods often create other challenges, such as static charging of surfaces or environmental pollution.
