Chemical etching is the high subtractive precision manufacturing process which uses temperature’s baths regulated etching chemical to remove material in a selective way to produce the high precision metal of any preferred shape. Etching process removes the layer of a metal that allows to embed the paint or ink into a nameplate in an area which was etched away. The etched area become the integral, permanent portion of a nameplate. The process is best for the harsh environments and can last for at least 7 years while in the field, which will depend on the conditions, regularly much long.
If paint or ink is removed from the etched nameplate, data on a plate remain visible in areas which are etched that extends a life of a nameplate radically. This makes the process suitable for the most environments which are volatile. Compared with other techniques of micro manufacturing like Stamping, CNC, EDM, Water Jetting, and Laser Cutting. Chemical Etching is cost efficient having more design flexibility, no debarring required, and shorter lead time. It is the optimal decision for the manufacturing of the precision metal part, apart from industrial production or prototyping.
The process of Chemical Etching can be determined in the series of the steps which include cleaning, lamination, exposition, development, etching, and also stripping, within which serious inspection is carried out automatically on every component.
The sheet of the desired material, name substrate, is laminated first with the light-sensitive resist layer. The photo resist layer is then exposed selectively to the UV light and advanced to obtain the positive product image. The product which is metallic is obtained once exposing patterned substrate to the etching solution that removes unprotected parts selectively from substrate. Each step is carried out at well controlled operating condition to make sure the end result is the best.
The consistency and degree of precision achievable offers the continuous etched chemically metal strip together with the mass production advantage substitute to a sheet etching process or standard panel or. The flexibility and excellent control enables reel-to-reel chemical etching method to design and also deliver parts which meet every set of the application requirement.
Chemical etching is the excellent methodology used to create high-precision metal parts which are multi-layered and complex. Also, it is the best process used to create straight, profiled edges or sharp, and the round holes. Like the purposive, viable option against the conventional stamping together with other processes of manufacturing, it allow the complex production and intricate the metal parts that cannot be achieved through any production method.
