What is Etching?

Etching can be defined as: a process in which an acid dissolves the unprotected parts of a metal surface to create a pre-determined object.

The chemical etching technique originated in 15th-century sword-making and is best known from the art world, such as in the etchings of Rembrandt van Rijn.
It was not until the 20th century, when the first photoresists (photosensitive coatings) came on the market, that etching was able to develop into an interesting precision production technique. Initially for copper, copper alloys and (stainless) steel alloys, it was later also used for specialised metals such as beryllium, gold, molybdenum, tantalum, titanium and silver, among others.

Using precision etching, Etchform produces thin metal precision parts customised to drawing specifications for almost every industry, including aerospace, mechanical engineering, medical engineering and (micro-)electronics.
