[0002] The anode water bladder used in electroplating is a critical component in the electroplating process, and its performance significantly impacts the plating results. Conventional electroplating water bladders typically consist of a bladder body with an inlet for injecting the plating solution and a square anode spray hole located on its periphery. The plating solution enters the bladder body through the inlet hole and is sprayed from the anode spray hole onto the area to be plated, completing the surface treatment of the product. However, these universal electroplating water bladders suffer from poor water discharge performance from the anode spray hole during electroplating, resulting in insufficiently uniform coating thickness.
