Photo etching, also known as chemical etching or metal etching, is a highly precise, tightly controlled corrosion process used to produce complex metal components with very fine detail.
Why use photo etching?
The photo etching process offers a cost-effective alternative to stamping, punching, laser and waterjet cutting when machining precision components from thin gauge metals – up to 1.5mm thick – including stainless steel, nickel and nickel alloys, aluminium, copper and copper alloys and hard-to-machine metals such as titanium.
When component integrity is critical, photo etching is often the only suitable metal machining technology as metal temper and magnetic properties are unaffected.
