Electroetching is the process of etching metals by utilizing the principle of anodic dissolution of metals in a liquid mainly composed of tap water or saltwater (under the action of electrolysis), and then turning on the etching power supply to achieve the purpose of etching. The commercially available electrolytic etching machines are all manual spray type and use saltwater as the etching solution. There are two types of power: large and small,
Advantages: No pollution, but only etching one step without pollution is not enough. Other processes must also be pollution-free, suitable for experimental production and small area etching of concave characters. Mainly used as a research experimental machine, or simply etching marks on metals, also known as electrical marking.
Disadvantages: Uneven etching surface, slow corrosion rate on large areas, cannot be used for mass production, cannot do large-area etching of raised characters, and cannot be used for large-scale production and processing of labels. Due to the fact that electrolytic etching is formed under the condition of metal conductivity, our product will also be etched on the side at any depth during etching, causing many fine patterns and text to be etched and 'rotten'.
