Description

Technical Field

[0001] The utility model relates to the field of equipment for a continuous electroplating production line for surface treatment, in particular to a precision electroplating jig for a universal wheel for line plating. Background Art

[0002] Surface treatment is a process that artificially forms a layer on the surface of a base material with mechanical, physical, and chemical properties that differ from those of the base material. The purpose of surface treatment is to meet the product's corrosion resistance, wear resistance, decorative or other special functional requirements.

[0003] Electroplating is a primary method of surface treatment. To improve productivity, continuous electroplating lines are essential equipment in the electroplating process.
