Photochemical Etching & Milling
Also known as photo etching, photochemical milling, and chemical milling, photochemical machining (PCM) is the process of fabricating sheet metal components using a photoresist and etchants to corrosively machine away selected areas.
Design Guide
For Flat Parts Photo Etching
When designing a component to be manufactured using photochemical machining (PCM), it is important to understand how the photo etching process can affect part geometry, tolerances, and feature size. Unlike stamping, laser cutting, or conventional machining, photo etching removes material chemically rather than mechanically, allowing complex flat metal components to be produced without burrs, heat-affected zones, or tool-induced stress. The result is a highly precise manufacturing process capable of producing intricate features while preserving the base material’s mechanical properties.
The Etchit Advantage
