PURPOSE:To bring every place of the materials to be treated into contact with a treating soln. and to satisfactorily progress the treatment by subjecting the treating soln. to vibrating and stirring and also vibrating the materials to be treated by a vibrating motor via a holding tool for material to be treated. CONSTITUTION:At the time of filling the plural materials to be treated into a cage or a porous vessel, immersing the same into a treating soln. and executing surface treatment, the treating soln. is vibrated and stirred, and the materials to be treated themselves are also vibrated via a holding tool for a material to be treated by a vibrating motor. Moreover, as the surface treatment, degreasing for working machine parts or the like, water washing; degreasing before coating, water washing; treatment before plating, treatment after plating; cleaning for electrical part such as semiconductors; chromating treatment; electrodeposition coating; acid-alkali treatment or the like are adopted, and as the vibration, in the horizontal direction and vibration in the vertical direction are adopted. Thus, every treatment can extremely uniformly be executed to the materials to be treated.
【目的】 本発明の目的は、処理浴を振動撹拌すると同 時に、被処理物自体にも被処理物用保持具を介して振動 モータによる振動を与えることによって、被処理物のど の個所とも均一に処理浴が接触できるようにする点にあ る。
【構成】 処理液を振動撹拌すると同時に被処理物自体 にも被処理物保持具を介して振動モータによる振動を与 えることを特徴とする表面処理方法。
