What is metal etching?
etching, from the German word, which means "to eat", cuts to the surface of the material by means of acid. Ethes are carried out on various materials, including glass, plexigans and metal. In particular, metal etching is the technique of industrial production, art and technology for branding and identification of real estate. The etching was a technique used by many European artists, including Albrecht Dürer, Francisco Goya, Rembrandt and James A. McNeill Whistler, to gain printers before further trials. Daniel Hopfer and URS Graph were early metal etching, but Dürer is credited as responsible for metal etching in the sixteenth century, when etching became an artistic form. Metal etching was first made on iron, but about 1540 copper etching began to prevail.
Method of etching on metal can be the chemical process of USING acid, photochemical process or electrochemical process. The basic technique of etching acid metals is to apply resistance to the metal plate areas, either to the entire board or isn to an area that one does not want to remain untouched. Parts of the metal to be etched are not either covered, or the resistant material is scratched from them using tools such as etching needle and ouchoppe.
The metal plate is then immersed in acid, which is uncovered with the surface of the metal and creates lines. To create printing, the resistance is cleaned and the surface is arrested. When the surface is wiped, the ink remains in etched lines and can then be captured on paper when it is made by a specialized print press. The depth for the changing line is performed by regularly removing the plate and covering the lines that have reached the desired depth of the resistance material. This is also possible to expire acid to the plate directly rather than bathing.
Etching of industrial metal is also called "chemical grinding". It is used in semiconductor production, industry industry with circuits and in fashion aircraft components to the aerospace industry. Photochemical etching isVariations in this process, in which the photolitograph is a method of creating a pattern. It is used in the world of the art world of Ostrom Glass & Metal Works. Electrochemical etching has been developed for the aerospace and automotive industry at the age of 20, and only recently expands to use in medical technology and use in the artistic environment. It is used by artists such as Cedric Green.
