Is an exceptional manufacturing process that produces the most intricate burr free, stress free, high precision profiles in a vide range of metals, working directly from low cost photo tooling.

The photo etching process, also known as chemical milling, basically consists of controlled removal of metal particles through a combined chemical and physical action.
 
Starting from a drawing that describes a customer’s design, a photo tool is generated by CAD software, and the negative of the shape of the part is impressed by light exposure on a thin photo-sensitive film, which is attached to both sides of a metal sheet.
 
After a developing phase in which film zones that have not been exposed to light are removed, the sheet is ready to enter the etching machine where a special acid will dissolve the polymerised zones and the final shape of the part is achieved. The size of the metal sheet is such that it may contain multiple parts (sometimes hundreds or even thousands), so as to lower the cost of the part as much as possible.
