Plating hanger for obtaining homogeneous plating

Abstract

A plating hanger is provided. The plating hanger provides a homogeneous plating by equalizing high current and low current zones by changing distances of part connections holding materials to be coated to an anode. The plating hanger includes at least one hanger frame, and a hanger body having part connections holding the materials to be coated on the plating hanger

What is claimed is: 
     
         1 . A plating hanger for a homogeneous plating of materials to be coated by an immersion method comprising
 at least one hanger frame, and   a hanger body having part connections holding the materials to be coated on the plating hanger, wherein   the material to be coated in low current zones of the plating hanger are attached on a first part connections of the part connections, and lengths of the first part connections are kept long and thereby approximated to an anode, and   the material to be coated in high current zones are attached on a second part connections of the part connections, and lengths of the second part connections are kept short and kept away from the anode.   
     
     
         2 . The plating hanger according to  claim 1 , wherein both sides of the plating hanger have a convex form from edge parts of the plating hanger towards middle parts of the plating hanger. 
     
     
         3 . The plating hanger according to  claim 1 , wherein the hanger body is within the at least one hanger frame the materials to be coated are hanged on the at least one hanger frame, and the hanger body is monolithic and filled with a conductive plate. 
     
     
         4 . The plating hanger according to  claim 1 , further comprising a hanger head, wherein the hanger head enables to be attached to a busbar and determines a direction and a density of a current. 
     
     
         5 . The plating hanger according to  claim 4 , wherein the hanger head comprises at least one hanger head busbar connecting terminal designed in a U-shape to determine the direction of the current. 
     
     
         6 . The plating hanger according to  claim 4 , wherein the hanger head comprises a hunger head frame connecting body to distribute the current on the at least one hanger frame at an equal density. 
     
     
         7 . The plating hanger according to  claim 6 , wherein the hunger head frame connecting body has two long edges extending at a certain angle towards right and left upper corners of the at least one hanger frame and short edges extending towards the at least one hanger frame such as to be in a parallel from a middle of each of the two long edges ( 14 . 2 . 1 ) to an other edge to distribute the current to the at least one hanger frame at the equal density.
