The annealing process that is still frequently used in various industries is extremely time and energy consuming compared to Openair® plasma pretreatment. Often products like aluminum foils need to be cleaned of light greases are treated in annealing ovens for several days at high temperatures to degrade and evaporate oils and greases.

Because of the especially effective heat transfer in the plasma process, the combination of Openair® plasma cleaning with the annealing process results in a significant reduction in process times. In fact, they are reduced from 72 hours to 10 minutes! And thermal treatment can often be eliminated completely.
