Facts about Chemical Etching
The chemical etching process is highly popular across a multitude of industries, for a number of reasons. First and foremost, it is a highly precise and accurate way of manufacturing; it is stress-free on the metal used and lastly, it offers a fast turnaround in a cost effective manner. We offer a broad variety of methods to manufacture parts and components for our customers. However, this method remains the most common.
To see exactly why chemical etching is a vital part of the manufacturing industry, please read on for some facts about the process and the ways in which it is used!
- The chemical etching process manufactures parts and components that are entirely free from burrs
- Because the nature of the process is very gentle, the metal that is used to create the end product is stress-free, which results in parts that are less susceptible to damage
- The chemical etchant is often ferric chloride as this can corrode a broad variety of metals, no matter how hard they are
- Other acids are also used for metals that do not corrode well with ferric chloride, such as ferric nitrate for Silver & Molybdenum
- The chemical etching process can be used to achieve the most detailed, complex and intricate designs with ease, no matter how big or small
- The process works with a wide variety of metals such as silver, nickel, nickel silver, aluminium, stainless steel, copper, brass, beryllium copper and much more
- Design changes are easy to make as it simply involves amending the drawing revision that is then printed onto the metal sheet before the etching process begins. A video of this process can be found here
- Accuracy is vital when it comes to creating parts and components. The etching process is highly accurate with tolerances of +-0.010mm, depending on the material used and how thick it is
- The thickness of the metal used also determines how fast the etching process is
- The chemical etching process is very cost effective because you can use one sheet to create a great number of parts, determined by size
- That being said, if a thicker metal part is desired, the process takes a little longer, thus driving up the price
If you need to make use of our chemical etching process; either alone or in conjunction with any of our other metal component processes, then please do not hesitate to contact us to discuss your requirements.
