DECORATIVE CR PLATING PROCESS FOR A RACK OF WHEELS
Title: Simulation of a decorative Cr plating process for a rack of wheels
Bath Type: Decorative chromic acid Cr (VI)
Applied software tool: Elsyca PlatingMaster
Validity and Reliability: Correlation between simulated and measured layer thickness values is well above 80%
Goal of Simulations: Drastically speed up rack design
Customer Benefits: Productivity improvements, time & cost savings
Decorative Cr plating processes produce highly non-uniform current density and layer thickness distributions. Rack design by trial-and-error will often require huge labour costs, mainly due to the large number of adjustable configuration parameters: number of parts in the rack, orientation and position of the parts, shape, dimension and position of screens and/or current thieves, etc. An entire trial and error run (rack design - rack manufacturing - plating - measuring layer thickness distributions on some parts in the rack) might take easily one week or longer. In contrast, defining the rack configuration from figure 1 in the SolidWorks CAD environment takes only a few hours, with another 1 or 2 hours to compute the resulting layer thickness distribution (figure 2) with Elsyca PlatingMaster. Hence, using Elsyca PlatingMaster will dramatically reduce the number of experimental trial and error runs, saving precious money and time.
