　　Metal signage etching: Metal signage is a carrier of advertising promotion, which has strong visual impact, eye-catching, and aesthetic characteristics, so it is widely used outdoors and indoors. There are many methods for making metal signs: screen printing, pad printing, etc. But among them, etching process is the most commonly used and also the lowest cost process.

　　Metal etching plate is a method of printing text or patterns onto the substrate through corrosion. Its principle is to use chemicals to react with the copper plate to generate acid resistant copper salts (c2+), thereby forming a protective film to protect the copper plate from oxidation; In addition, Hydroxide ion ion can be generated by electrochemical method to further prevent the generation of oxidation reaction.

　　Traditional metal etching plates are manufactured and processed manually, with low efficiency and difficult quality control; The current industrial production method can effectively solve this problem: using computer-controlled engraving machines to engrave the surface of the steel plate, laser drilling technology is used to transfer text or patterns to the surface of the steel plate, and CNC machine tools are used to complete the final polishing and painting processes to produce the finished product.

　　In the practical application of metal signs, we can customize products of different specifications and sizes according to customer needs to adapt to different application scenarios; At the same time, we can also provide products in various colors to meet customers' personalized needs.
