Know How Metal Etching Is An Integral Part Of Industrial Processes

When it comes to machines and their parts for industrial use

, strength and quality play a crucial role. This is where metal etching is increasingly playing an indispensable role. Did you know that the word etching is derived from the German word which translates to to eat? In fact, thats what etching is all abouteating into metals with the use of specially created chemical solutions. Interestingly, etching is also used to create various forms of art. Not being limited to metals, etching can also be done on glass and Plexiglas. However, etching on metals remains an integral part of the industrial and manufacturing process. These metals are also resistant to high amounts of heat, just like conductive foam is.

How is metal etching carried out?

As we have seen, this method essentially makes use of metal and some advanced acids (or chemicals) that have the capability to eat into the metal. The etching process is carried out by using an acid, an electrochemical process or a petrochemical process. To initiate the etching process, a special coating of an acid or chemical resistant material is applied to the parts that need to be kept intact. The parts to be etched are not covered with the resist.

Then, the metal plate is dipped into acid which eats into the exposed part of the metal to give the desired shape to the metal. There are several techniques by which one can create etching effect of varied depths and textures. Sometimes, measured amounts of acids are applied or sprayed upon the plate instead of dipping the entire plate into acid. This process is also known as chemical milling. EMI products are also created by etching.

What are the various uses of metal etching?

This process helps create printed circuit boards. In addition to this, metal etching comes in handy when semiconductor devices need to be created. Metal etching on glass is a widely used technique to create architecture or interior decoration products. In addition to this, etching of metal is usually carried out in order to create specimen of metals for microscopic observation.

Along with etching, in an industrial set up you might also need to make use of conductive foam. These are ideal for controlling electromagnetic interferences. These are often wrapped in a copper fabric that is also nickel plated for higher durability.

EMI products such as strips, shields, contact rings etc are also created by etching metals. These diminutive components come in handy in several applications. Most of the etching finished products can now be ordered online because a number of these manufacturers have established their online presence.
