Hello, stainless steel is one of the most widely used metal materials in industry. At present, the main etching processes are: laser etching, electrolytic etching and chemical etching.

1. The advantages of chemical etching are fast etching speed, adjustable etching depth and good etching accuracy.

2. Electrolytic etching: the workpiece is used as the anode, and the electrolyte is electrified to dissolve the anode, thus achieving the purpose of metal etching.

3. Laser etching processing. Laser etching is an etching method that uses a laser machine to carve and cut metal. Its advantages are neat and straight edges, no side corrosion and relatively simple process. The disadvantage is that the machined metal contact surface will be damaged to a certain extent, and the workpiece with thick thickness is prone to burning sensation, and the cost of batch processing is about twice as high as that of chemical etching.
