Photochemical machining (PCM) is a highly precise, chemical-based method for producing complex metal parts. By combining advanced phototools, specialized photoresists, and controlled chemical etching, this process allows Switzer Manufacturing to produce intricate components with excellent dimensional accuracy, burr-free edges, and minimal material stress. PCM is ideal for designs with fine detail that would be difficult or costly to achieve using traditional machining or stamping methods - or for any component that demands exceptional precision.
