Chemical Etching is the process of using acids, bases or other chemicals
to dissolve unwanted materials such as metals, semiconductor materials
or glass. This process has been used on a wide variety of metals with
depths of metal removal as large as 12mm (0.5 in). Selective attack by
the chemical reagent on different areas of the workpiece surfaces is
controlled by removable layers of material called masking or by partial
immersion in the reagent.
This process can offer economical alternatives to stamping, punching, laser or water jet cutting, or wire electrical discharge machining (EDM) for thin gauge precision parts. The tooling is inexpensive and quickly produced.
Chemical Etching fulfills the design of 3D patterns on casing and enhances the touch feeling of handheld roducts.
