Method for treating surfaces of geometrically complex parts, part-carrying device and treatment device
View Patent ↗A part-carrier for electrolytically treating geometrically complex parts includes a reinforcement vertically supporting supports that are movable in rotation and designed to carry the parts to be treated, and a control member which, when activated, pivots the movable supports in sequence to either side of a neutral initial position. Application to electroplating.
1. A method for electrolytic or anodic oxidation surface treatment comprising the positioning in a neutral initial position, by means of a removable part-carrier, geometrically complex parts constituting a first electrode, in a treatment bath contained in a tank including one second electrode of polarity opposite to that of the first electrode, the geometrically complex parts made of metal or metallizable plastic material, wherein:
a) the geometrically complex parts are such that, in a neutral initial position at 0 degree; and
b) during the treatment of the geometrically complex parts, the geometrically complex parts are subjected to sequential rotations on either side of their neutral initial position by an angle up to 90 degrees, so as to increase the exposure to lines of current established between the first and the second electrode during the implementation of the treatment method;
wherein the geometrically complex parts to be treated are held in different angular positions resulting from the sequential rotations during a determined time as a function of the treatment and of the geometric complexity of the parts.
2. The method of claim 1 , wherein the angle of rotation of the geometrically complex parts is of 45 degrees on either side of the neutral initial position.
