Precision photochemical etching and chemical milling for complex metal components. Delivering exceptional quality parts for aerospace, electronics, medical, and automotive industries with tolerances as tight as ±0.001″.
Metal etching, also known as photochemical machining (PCM) or chemical milling, is a precision manufacturing process that uses controlled chemical reactions to selectively remove material from metal sheets. This advanced technique produces complex, burr-free parts with exceptional dimensional accuracy and surface finish quality.
Achieve tolerances as tight as ±0.0005″ (±0.013mm) with exceptional repeatability
Chemical process eliminates burrs and tool marks for superior surface finish
Create intricate patterns and shapes impossible with traditional machining
No heat affected zones or mechanical stress, maintaining material properties
