How stainless steel etching works 17/3/2021
When compared with conventional sheet metalworking, it has a number of inherent advantages, key among which are its ability to produce parts without degrading material properties – no force or heat is used during processing – and almost limitless part complexity as component features are removed simultaneously using etchant chemistries.To get more news about etching stainless steel, you can visit stainless-steel-supplier official website.

The tooling for etching is digital, so there is no need to start cutting expensive and difficult to adapt steel moulds. This means that large quantities of products can be reproduced with absolutely zero tool wear, ensuring that the first and millionth part produced are exactly the same.
The economy and adaptability of photo-etch tooling is a key stimulus to design freedom, along with its ability to produce complicated products. As the cost of creating prototypes is low there is no barrier to entry, and complex designs can be produced in a matter of days.

Etching is suited to pretty much any stainless steel component between 0.01mm and 1.5mm in thickness, but below are some example case studies of the more prevalent product groups where photo chemical etching stainless steel adds value.Meshes, filters and sieves. Unlike conventional machining technologies, chemical etching offers greater levels of complexity when producing thin, precision steel meshes, filters, and sieves.

With metal removed simultaneously when etched, multiple aperture geometries can be incorporated without incurring high tool or processing costs, and where punch-perforated sheets are prone to distortion, photo-etched mesh is burr and stress-free with zero material degradation.A 150-micron thick precision stainless steel mesh used in radiation detection devices is etched by Precision Micro to close tolerances – below the standard ±10% material thickness – and features a critical honeycomb shaped mesh array.

Given the size of the mesh, more than 600mm x 600mm square, stamping was seen to be uneconomical due to the investment required in press tooling, and laser cutting could not achieve the required tolerances, especially over such as large surface area, and also produced undesirable burring around each mesh opening.

Another benefit of etched stainless steel mesh is that the process does not alter the surface finish of the material – no metal-to-metal contact or heat source is used which can mar the surface – offering a highly aesthetic finish. Automotive speaker grilles with complex hole arrays and surface engraving are supplied by Precision Micro to automotive OEMs in quantities of multiple millions each year, the tooling too complicated for stamping and the mesh pattern too complex to laser cut.
