At Tecan, we are exceedingly proud of the work we have put into developing our aluminium etching process. With this process, we can now produce high-quality etched aluminium parts with great dimensional accuracy and a superb cosmetic appearance – allowing us to confidently offer large production volumes with great consistency. Thanks to our continuous improvement efforts, our ability to control and certify the entire etching process have grown significantly allowing us to achieve remarkable results.
what is aluminium etching?
Aluminium has long been used in many varying industries thanks to its properties; low density, high thermal conductivity, non-toxic and resistance to corrosion to name just a few. So it stands to reason that we’d also want to employ aluminium in our etching process.
Etching aluminium is a process that does require specific knowledge of etchants as it’s an easy metal to get wrong with an incorrect etchant. This is why at Tecan we have precise solutions and environments for etching aluminium to ensure that the process is a seamless one. With the correct process, aluminium can be cut to exact measurements and shapes to a higher degree of accuracy than traditional tooling or laser cutting.
The above goes for etching stainless steel too: an industry-standard metal that again has fantastic properties to make its use in diverse fields a necessity. Stainless steel is, in fact, so versatile that even after the chemical etching process, it doesn’t need finishing. This also translates to a quicker overall production time. Chemical etching (also known as photo chemical etching and photo chemical machining PCM) reduces the production period anyway thanks to digital tooling which allows for this time to be reduced from weeks and months (like laser or machine tooling) to days.
