What is Photo Chemical Machining?

Before diving into its applications, it's important to briefly understand the PCM process. PCM involves coating a metal sheet with a photoresist, which is then exposed to UV light through a photomask with the desired design. The exposed areas act as a stencil to protect parts of the metal during the chemical etching stage. Once etched, the metal is left with intricate and accurate designs.

This process is ideal for creating parts with fine details, high precision, and tight tolerances, which are critical in industries like electronics, aerospace, medical devices, and automotive. However, despite its technological significance, PCM’s contributions are rarely appreciated in the context of everyday products.
