The invention belongs to the field of metal electroplating, and particularly relates to an electroplating energy-saving method. The electroplating energy-saving method comprises the following technological process of racking, cathode degreasing, anode degreasing, washing, washing, washing, activation, washing, washing, antipole operation, electroplating, recycling washing, recycling washing, washing, draining and taking down. According to the washing process, a circulating water treatment system is included, and recycling of water resources in the production process can be achieved; according to the electroplating process, an automatic dosing machine, a filtering machine, an electric control ampere meter and a temperature alarm device are added into the electroplating process. The time in the electroplating process is controlled to 30 minutes to 60 minutes. The electroplating energy-saving method has the beneficial effects of being reasonable in process setting and ideal in electroplating effect, achieving recycling and reutilizing of energy resources, saving production cost and reducing the pollution to the environment.
