Chemical Etching Metal

A mask or resist is applied to the surface of the material and is selectively removed exposing the metal to create the desired image.

Chemical etching metal.

Chemical milling or industrial etching is the subtractive manufacturing process of using baths of temperature regulated etching chemicals to remove material to create an object with the desired shape. Choosing the right etchant etchant is the chemical or mixture of chemicals that you ll use to cut into unprotected parts of your metal and create the finished etched design. Chemical etching another industry name for photo etching and photochemical etching is a cost effective manufacturing process for a variety of industrial thin metal parts. Why using chemical etching.

Although not as fine a metal as copper steel is finer than zinc and it is also more durable particularly when used as a printing plate. See all gauges of metal blanks for more options. Chemical etching sometimes referred to as photo etching or photochemical machining is a metal machining process which uses chemical enchants to create complex and highly accurate precision components from almost any metal. When a part of 200 μm is chemically etched deviation can be up to 20 μm 0 02 mm.

It was developed from armor decorating and printing etching processes developed during the renaissance as. Because copper and zinc have gone up in price many artisans who etch designs in metals have turned to etching steel. The chemical etching process is one that involves very little stress on the metal sheets that we utilise. Chemical etching is a method of engraving that uses a high pressure high temperature chemical spray to remove material to create a permanent etched image in metal.

What is the difference between the etching methods we offer. Chemical etching is highly suitable when you want to create complex multi layer high precision metal parts. 24 gauge sheet metal and 24 gauge pre cut blanks will also work just be sure to leave 24 gauge items in the chemical bath for less time than you would a thicker metal. Chemical etching and laser etching both are available for stainless steel black metal brass finish and copper finish materials.

There are two different processes we use to etch into the metal. By using chemicals to dissolve the excess or unwanted portion of the material rather than simply cutting it away you are left with smoother more precise edges. A common question we receive regarding our various production processes is. This means that unlike other processes that require bending and cutting the end product is a lot less vulnerable to damage when it comes to being used.

The photo etching process is ideal for the precision machining of parts with simple to complex designs. Tolerance on etched features is typically 10.
