Copper Photo Chemical Etch/Photo Chemical Machining

Writer: admin; Source:SinoGuide Team; Date:2017-05-12

Summary: SinoGuide provides Copper etching, Beryllium Copper, Brass, Bronze, Phosphor Bronze, Photochemical Etching in China; Photoetching is effective for many kinds of sheet metal machining


SinoGuide offers brass chemical etching of high precision, very thin metal foils. We machine foils with excellent feature and tolerance control and have earned a reputation for manufacturing high quality components that meet the most demanding specifications. We can successfully etch production Stainless Steel components that are 0.005 inches thick. We can also photo etching brass as thick as 0.040 inches.

Copper etching, Beryllium Copper, Brass, Bronze

Metal Photochemical machining is known by a number of names including photo etching, PCM, chemical etching, and chemical machining. All of these names describe the same precision metal etching process. We use a stencil, which we call a photo tool, to expose multiple images of the parts on both sides of a sheet of raw material that has been coated with a light sensitive and acid resistant material, called “resist.” After the images of the parts have been developed, and the uncured resist washed away, we etch the metal around the parts by dissolving it in a ferric chloride solution. The resulting parts have no burrs or deformations of the raw material that can occur with other processes such as punching, stamping, and waterjet or laser-cutting.

The photo chemical etching process is frequently the process of choice because the tooling is inexpensive and can be produced very quickly, the parts are very precise and consistent, and the metal etching process is particularly effective when the shape of the part is complex and/or the part contains many holes or internal cut-outs.

Brass Meshes and Filters

Metal meshes and filters are photo chemically etched from brass or other metals, in thousands of different shapes and sizes, and most can be manufactured using our photo etching process.
 
Metal meshes are often used to screen unwanted things such as insects; metal filters are used in filtration, such as in the food and beverage industries. Different patterns and arrays of holes can be produced at no extra cost and tighter tolerances can be achieved by the etching process.
 

Many metal alloys can be etched

 
Photoetching is effective for many kinds of metal. Ferrous alloys (steel), aluminum, cuprous alloys (including copper, brass, bronze and copper nickel, beryllium copper and more), nickel and nickel-iron alloys, molybdenum and more are suitable for custom photochemical machining services. Photo etched brazing alloy preforms are gaining popularity in aerospace and other industries.
