Etching metal, adopted the etching process, is a new kind of metal material for decoration and other applications. Etching, derived from an ancient Germanic word 'eat', is the process which transferring graphic elements onto the surface of metal plates. Generally, the metal will be etched on one side. However, both sides of the metal can be etched if desired. What's more, almost any metal and any graphics can be etched. And the etching graphics will never fade, since the graphics are etched directly onto the metal surface. At the same time, the etching process can create a shallow emboss making it possible to create highly decorated objects without compromising the structural integrity of the metal.
At the beginning, we prepare the graphics and raw material according to customers' requirements. Second, we will clean the metal through acid washing for removing the oxides and rust things on the metal surface. Third, we will dry the metal material, cover the metal with photosensitive dry film or plastic coating and then dry the metal again. Fourth, through exposure and development, the graphics will be removed on the metal plate. Fifth, we will use the chemical solution corroding the section without protective layer. Finally, we remove the protective layer and dry the metal plate.
How to choose the metal material for etching?
Mentioned above, almost any metal can be used for etching. But there still exists some differences. Copper is a traditional and still preferred metal for etching. Because it can bites evenly and holds texture well. At the same time, the color of the ink will not distort when wiping. Zinc, cheaper than copper, but sometimes does not bite cleanly and evenly as copper and it changes some colors of ink. Steel, incredibly durable and cheaper than copper and zinc, is gradually popularity as etching material.
The main application of etched metal is decoration. With unique and artistic graphics, the visual effect of etching metal is extremely attractive and extravagant. Precision industrial parts, also can be made of etched metal through acid etching and photo etching. In addition, etched metal also can be used for name card, business card or any other identification cards, metal bookmark, etc.
The maintenance of etching metal is simple. For easy cleaning stains or dust, you just need to wipe or clean by using soft cloth. For graffiti and other discolorations, you can use the mild soap and mild water and then dry it by soft cloth. When it comes to the stubborn stains, you can use the pressure washing and approved cleaner.
