What is photo etching?
Photo etching is a highly precise, tightly controlled corrosion process used to produce
complex metal components with very fine detail.
Photo Etching / Chemical Etching (also known as Chemical Milling, Metal Etching, Acid Etching, Chemi Etching, Chem Etch & Photo Chemical Machining (PCM) uses a combination of photographic digital tooling and chemical processes to image and etch the metal to shape.

Why use photo etching in China?
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.
