Customer requests to improve corrosion performance on engine dampers led to ACC recommending a transition from iron to zinc phosphate for the pretreatment process. However, the effect of zinc phosphate on ground surface areas can cause a dimentional change affecting fit and function.
THE SOLUTION
Subsequently, ACC developed innovative methods of pretreatment that introduced masking for the zinc phosphate pretreatment process with consistent repeatability and proven performance at high volumes.
