What is Etching?
Etching is a precise manufacturing process that uses chemical solutions to selectively remove material from metal sheets, creating intricate designs, patterns, or micro-features without affecting the material's inherent properties. It is ideal for producing burr-free, stress-free, and high-precision thin metal components.
