Hanging device for anodizing

Abstract

An exemplary hanging device for fixing workpieces for anodizing, includes a support frame, a hook module, and a resilient member. The support frame includes an upper frame portion and a lower frame portion formed at opposite ends thereof. The hook module includes a number of connecting hooks. The resilient member is fixed to the lower frame portion. The hook module and the resilient member are made of a conductive material. The hook module is configured for connecting workpieces in series via the connecting hooks. A first end of the hook module is hung on the upper frame portion and a second end of the hook module is connected to the resilient member. The resilient member is capable of creating an elastic force to tighten the workpieces to the hook module.
