　　Firstly, metal refers to a single substance with luster and ductility, which is easy to conduct electricity, heat transfer, and other properties. Except for mercury, it is a solid at room temperature, such as gold, silver, copper, iron, manganese, zinc, etc.

　　Etching, on the other hand, is a processing technique that removes materials through chemical reactions or physical impacts.

　　So, etching a sign refers to a metal sign with raised or concave characters made by processing it on metal through several steps such as masking, etching, painting, and coloring. Etching technology can be divided into two categories: wet etching and dry etching.

　　The materials used in the etching process of signage include stainless steel SUS201, SUS304, SUS316, and SUS430, mirror stainless steel, brass, stainless steel, and other materials. The most commonly used materials are generally stainless steel or brass, and of course, brass is much more expensive than stainless steel.

　　The main process of etching labels includes cutting, making mask layers, etching/etching, peeling, painting, filling colors, and applying varnish.

　　Advantages: Clear etching pattern, beautiful and generous appearance, strong metallic feeling, simple processing technology, cost saving, and faster efficiency.
