The process

What is chemical etching?

Chemical etching, also known as photo etching or metal etching, is a highly precise, tightly controlled corrosion process used to produce complex metal components with very fine detail.

Unlike traditional sheet metalworking, no mechanical force or heat is used during the chemical etching process. This means material properties are unaltered and etched components are free from stresses and burrs.
