For more than 37 years, our know-how and our technologies meet the majority of the specifications of our customers.
Engraving, cutting, folding, bending, surface treatments and thermal treatments, our solutions are present in many sectors: Aeronautics, defence, connectivity, luxury, models, optics, mechanics, electronics, Medical, etc.
The main metals used for the chemical etching are copper, brass, the nickel silver, copper beryllium, stainless steels, the Pinchbeck, nickel and many others in different shades.
The chemical etching. What is it?
There are several types of engraving, each with its advantages and disadvantages. The chemical etching is a method for etching by chemical attack. The object is immersed in a chemical solution, which will attack the surface of the wafer that is not protected. Used acid changes depending on the composition of the substrate.
This technique has several advantages, among which, particularly high rates of engraving. What makes quick burning and helps preserve the protective layer. A chemical etching reacts with certain materials.
On the other hand, this engraving is highly isotropic, acid attacks the substrate in all directions, giving a profile of almost hemispherical engraving.
Quick and simple, it is a well technique suited for burn quality with a series of objects, so what makes economic.
