Chemical etching is indeed a form of etching that removes material and leaves a permanent engraving on metal using a high-pressure and relatively strong chemical spray. To produce the desired image, a mask or resistor is added to the material’s surface and then removed, with the option of exposing the metal.
The milling machine controls the corrosive reaction between the chemical and the material and reinforces the effect by heating the solution and spraying it with high pressure. The chemical spray melts unprotected areas of metal to atomize the material and provide a smooth, peeling surface.
What does this process involve?
Simply put, the metal being corroded by an acid solution, leaving engraved shapes or projects behind. A photo-resistor is built into each sheet to shield the project from acid. When the acid is added, it dissolves the remaining metal until the project is all that is left.
What results from chemical etching?
Chemical etching produces hundreds of pieces and objects that we will encounter on any given day.
Jewelry, washing machines, pieces of rice cookers, cell phones, televisions, airplanes, cars, and even batteries all play a role in our sculpture industry.
Do you guarantee high quality results?
Chemical engraving is a process where the metal plates used are subjected to very little stress. This ensures that, unlike other methods that involve bending and cutting, the finished product is less likely to be damaged as it is applied.
In addition, there are no burrs or edges on any part or item that has undergone our metal milling process. Some errors can be detected and easily corrected before costing errors due to repeated methods of inspection and part inspection. In addition, this is one of the most accurate processes in the industry and therefore produces high quality results.
The flexible methods used in this process allow us to accurately create complex and complicated projects that often cause material damage if used in any other process.
• Chemical etching outperforms hard tooling manufacturing methods like stamping and die cutting in a number of ways. It has a lot of feature versatility which costs a lot less to set up. There is no mechanical distress caused by the etching process to the stone, resulting in sections that are free of burrs and tension, with no modifications to the grain structure
• Unlike with costly tool wear, there isn’t any heat distortion.
• Chemical etching can be used on nearly any form of metal and can handle very thin materials that would be impossible to deal with otherwise.
• The grain structure of the material and material structure are unchanged.
• Tight tolerances permit for the production of complex geometries.
Signage and industrial brands have never been more durable.
