Why the Metal Etching Process is Right for You

Here at Qualitetch, we utilise a lot of different processes to manufacture the parts and components that are right for our customers. One of these processes is metal etching.

Etching originates from a German word which means ”˜to eat’ and it refers to a process which is used to cut into the surface of any material – in this case, metal – using an abrasive acid.

This process can be used in a range of metals such as steel, aluminium, copper, brass, nickel and silver amongst many others. Originating as an industrial technique which was used widely to brand and identify products and property, the method itself is now carried out by experts for a range of different industries.

How does it work?

The chemical etching process is relatively simple.

A photoresist is applied to the specified areas of purified sheet metal, covering a template or design that needs to be etched out of the metal.

The metal sheets are then passed through a series of acid washes. The acid acts as an etching agent and is usually ferric chloride. The acid etches away at the exposed metal, leaving behind a part in the metal that remains.

The sheet metal is then rinsed and dried before the photoresist is removed and then finally cleaned once more.

Uses of the Metal Etching Process

As previously mentioned, metal etching is used to manufacture a range of different parts and components for an extensive list of industries, including Aerospace, Automotive and Telecommunication. The parts that are needed for these industries, especially Aerospace, are required to be of an exacting standard, every time.

Here at Qualitetch, we have received aerospace accreditation which guarantees our customers the highest quality products at all times.

A large proportion of our work requires us to create aerospace components, and parts for nanotechnology, shielding, medical technology and other industries and sectors that require precision and accuracy at all times.

This process is used widely because it not only provides flexibility to our customers – a trait which is vital when it comes to tight material tolerances, but it is also quick and easy to produce, without reducing the quality of the materials used.

One of the best things about this kind of component manufacturing is that it can be done on a wide range of metals without affecting the original mechanical properties and can be manufactured in days rather than weeks.
