Etched metal signs are one of the many types of metal identification signs. They are used in a wide range of applications, including daily civilian and commercial applications. The following will introduce the introduction and process flow of Etched metal signs by Jaguar Sign ( Over 20 years professional letter and sign manufacturer ).


1. Characteristics of Etched Metal Signs

Etched metal sign’s raw materials are usually aluminum, stainless steel and copper. Etched metal signs are used as a traditional metal sign. Because the product is characterized by stable and long-term use, can adapt to various outdoor environments and has the characteristics of corrosion resistance. It is suitable for harsh outdoor environments such as outdoor door number sign, vehicle and ship license signs, equipment and electrical namesigns, etc.


2. The process of Etched metal signs

The production of the corrosion process requires the creation of electronic documents, film production, and spraying of photosensitive blue oil, photosensitivity, development, paste of antiEtched film, constant temperature, and formation of characters and graphics after being etched by an etching solution. The process of drawing corrosion signs is more complicated, and it must meet the requirements of beautiful patterns, clear lines, suitable depth, flat bottom surface, saturated colors, and uniform drawing.


The specific steps are as follows:

2-1. Unloading: According to the size required by the drawing, plus four sides above 5mm. Shears require flat surfaces and perimeters.

2-2. Mechanical polishing: Use a polishing machine to mechanically polish the wool. The cloth wheel is 300-350, and the motor speed is generally 2000-3000 rpm.

2-3. Alkali treatment: cook the metal sign with 10-15% sodium hydroxide in 65-85 ° C aqueous solution for 10-30 seconds, then wash it with water, and immerse it in 5% aqueous sodium bisulfate solution.

2-4. Powder treatment method: Use a flat brush dipped in old powder to scrub the ears in a uniform cross-crush method to listen to it until the effect of removing dirt or oxygen skin is removed, and then block it with a 5% potassium dichromate aqueous solution.

2-5. Brushed finish: The surface of the metal sign is brushed with machine to achieve the regeneration effect of the metal surface.
