Background

When the aluminum component is anodized, a film does not exist at the position contacting with a hanger, and the parts are damaged or scratched at the position contacting with the hanger sometimes. The hanging and the electric conduction of the parts are realized by a fishbone-shaped aluminum or titanium alloy hanger, and the parts are clamped on the hanger by adjusting the angles of the parts. Part and hanger will be lightly put into the groove and tie up the couple and the conducting rod of hanger with the aluminium silk well before the circular telegram, and circular telegram anodization is from beginning to the end hanger is motionless, can cause the unable anodization of part outage anyway, and the part will be unable electrically conductive oxidation when anchor clamps and part contact move the anode film under the effect of external force. (the traditional clamp is a circuit which is electrified and a carrier for adjusting the angle of a hanging part.)
