Photo etching services have revolutionized the way precision parts are manufactured. This process offers a cost-effective, high-precision method to produce intricate metal parts for a wide range of industries. From aerospace to electronics, photo etching has become an essential manufacturing technique that provides unmatched versatility and accuracy.
What is Photo Etching?
Photo etching, also known as chemical etching or photochemical machining, is a subtractive manufacturing process that uses acid to selectively remove material from a metal sheet to create intricate designs, patterns, and shapes. The process begins with creating a digital design of the part to be manufactured. This design is then transferred onto a light-sensitive photoresist film that is laminated onto the metal sheet.
The metal sheet is exposed to UV light through the digital design, which hardens the exposed areas of the photoresist. The unexposed areas are then washed away, leaving behind a pattern of hardened photoresist on the metal sheet. The sheet is then submerged in an acid bath that selectively etches away the unprotected areas of the metal, leaving behind the desired part.
