What are the main points of the conventional plating hanger design: ①The material used to make the hanger should be stable and insoluble in the solution. ②There should be good contact measures between the hanger and the plated parts and the pole, especially the hanger with light-weight parts. ③The main pole and support pole combination hanger should not be connected by riveting, so as not to store the solution. ④Reliable insulation measures must be considered for the cathode and anode combination hangers. ⑤The hanging direction of the workpiece should be fully considered, especially the sharp corners and deep concave parts. ⑥Sufficient anode area and related requirements should be considered in the plating cavity of cylindrical workpiece. ⑦The design of the hanger should fully consider the versatility. Reduce the repeated design of similar parts using hangers. ⑧Ensure the current intensity that the hanger needs to pass when working. In case the cross-sectional area is too small to affect the normal flow of current. ⑨Convenient loading and unloading must be considered for all hangers. ⑩In addition to the parts in contact with the workpiece, insulation measures must be taken into consideration for other parts of the hanger. ⑾The mounting hanger must be firm and reliable, and the workpiece will not fall off the hanger during the whole process. ⑿It must be able to withstand the weight requirements of the workpiece to be hung, and it will not be deformed due to this. ⒀Because the covering surface of the hanger is too large, it will not affect the normal deposition of the coating. ⒁Consider whether there are mounting marks after the workpiece is mounted. |
