This invention relates to a treatment device for dyeing brass zipper heads to an antique bronze color. The device is used for pre-treatment of brass zipper heads to achieve this effect. It includes a mounting frame with several clamping components along its length. Each clamping component includes a first plate and a second plate, which are parallel to each other and used to clamp the zipper head. The mounting frame also includes a drive component for moving the second plate to rotate the zipper head. This invention employs fluid polishing to perform a thorough pre-treatment of the zipper head, improving its surface quality. While maintaining precision, it also reduces processing time and costs, and generates less waste liquid, resulting in less environmental pollution.
