First of all, metal refers to a simple substance with luster and ductility, easy to conduct electricity, heat transfer and other properties. Except for mercury, all solids at room temperature, such as gold, silver, copper, iron, manganese, zinc, etc.

Etching, on the other hand, is a process that removes materials using chemical reactions or physical impact.

Then, etched signs also refer to metal signs with raised or concave characters on the metal, which are processed in several steps such as masking, etching, filling and coloring. Etching technology can be divided into two categories: wet etching and dry etching.

Materials used in the etching process: stainless steel SUS201, SUS304, SUS316 and SUS430, mirror stainless steel, brass, stainless iron and other materials, the most commonly used are stainless steel or brass, of course, the price of brass will be much more expensive than stainless steel.

The main process flow of etching includes cutting board, making mask layer, etching/etching, film stripping, painting, filling color, applying varnish and other steps.

Advantages: clear etching pattern, beautiful appearance, strong metal feeling, simple processing technology, cost saving and faster efficiency.

In addition, the surface treatment of etched signs includes the following:

(1) Mechanical polishing

(2) Alkali treatment

(3) Powder treatment method

(4) Brushing treatment method

The main application areas of etched signs:

Consumer electronics industry (such as audio, Bluetooth headsets, air conditioners, washing machines, dishwashers, mobile phone shades, mobile phone receiver nets, stage lighting films, etc.)

Filtration and separation technology (such as tea drain, razor mesh, coffee filter, juicer mesh, speaker mesh, shower filter mesh, etc.)

High-end crafts (bookmarks, etc.)

Medical equipment (hydraulic gauge signs, etc.)

Precision machinery industry (various industrial fixtures, tools, etc.)

Car (car signage, car handset network, etc.)
