The advantages of two commonly used label etching machines in the production of etching machines

The commonly used sign etching machines in our daily life include chemical etching machines and electrolytic etching machines, as well as many other types. These mechanical equipment can generally be purchased in the advertising equipment procurement market. Let's take a look at the advantages of the two commonly used sign etching machines for sign making.

Firstly, chemistry Etching machine

1. The automatic chemical etching machines seen in the market today use high-pressure spraying and linear motion of the etched plate to form a continuous and uninterrupted feeding state to corrode the workpiece and improve production efficiency;

2. The effective area and etching uniformity of the sprayed and etched metal plate have been increased, which is superior to splash etching in terms of etching effect, speed, and improvement of the operator's environment and convenience;

3. After repeated experiments, the residual etching stains on the etched workpiece can be effectively removed by spraying at a pressure of 1-2Kg/cm2, which greatly improves the etching speed compared to traditional etching methods. Due to the recyclable liquid of this etching machine, this can greatly reduce the etching cost and meet the requirements of environmentally friendly processing

Secondly, electrolytic etching machine

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, with two different power levels.

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'.
