In chemical etching, a chemical solution is used for the purpose of etching by chemical reaction, one technique for removing a material by chemical reaction.
The etching machine is mainly used in the aerospace, machinery, and signage industries. The etching machine technology is widely used in the processing of weight reduction instrument panels, nameplates, and thin workpieces that are difficult to process by conventional processing methods. Etching is an indispensable technique in semiconductor and circuit board processes. It can also etch patterns, and geometric shapes on the surface of various metals such as iron, copper, aluminum, titanium, stainless steel, zinc plate, and other metal and metal products, and can be accurately hollowed out.
