Chemical Etching: Precision Metal Processing

Chemical etching, also known as photochemical machining (PCM), is an advanced subtractive manufacturing process that uses controlled chemical reactions to produce high-precision metal components. Unlike mechanical machining or stamping, etching removes material without applying force, ensuring stress-free and burr-free parts with exceptional accuracy.

Process Overview

The process begins with material preparation, where metal sheets such as stainless steel, copper, brass, nickel, or titanium are cleaned and coated with a photoresist. The desired pattern is then transferred onto the resist using exposure with UV light, followed by development to reveal the areas to be etched.
