電着塗装の膜厚シミュレーション

抄録

An electric current distribution analysis program, “Electroplating Pilot System” (EPPS), was developed, and has been sold. As an expansion of EPPS, a new program using the Finite Element Method (FEM) that allows users to calculate thickness distribution of electrodeposition coating was developed. By introducing new paint parameters for thickness calculation that considered special characteristics of electrodeposition coatings, actual thickness calculation precision was obtained. The experiment method to obtain paint parameters and parameter determination methods based on experimental measured data were indicated. Also, constant voltage coating testing on flat plates and calculated results of the testing were compared. Both total current and thickness matched well at each time frame.
