Description

Technical Field

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics. When performing electroplating operations, electroplating fixtures are required to clamp and fix the workpiece. Electroplating fixtures can generally only clamp workpieces with flat surfaces. When clamping curved workpieces, the clamping is not stable enough due to the low fit between the fixture and the workpiece, and the structure is relatively fixed, which is inconvenient to adjust according to the size of the workpiece, so there are certain limitations.
