Needed help on etching in metals
I am in need of help regarding photo chemical etching done in stainless steel and copper. The sheet we use is thin sheets. Please help me in sourcing the right chemicals and other guidelines to do a successful etch in the metals.

Well, I'll help to the extent of posting your inquiry, Vinod. But to expect to go from zero knowledge of a subject to successful commercialization via an internet posting is a bit unrealistic :-)
I think you need to align yourself with a local consultant or etching process supplier.

I think you might be wanting capillary film. I have been researching somewhat of the same thing. I need capillary film adheared to the mesh already.Sandra Obrien

Vinod, the chemicals you need are concentrated ferric chloride for the stainless steel and cupric chloride for the copper. You can ablso use ferric chloride with copper. As Ted says, to go from no knowledge to a successful process via the Internet is totally unrealistic as successful chemical etching is a complex science. There are also numerous health, safety and environnmental issues you will need to address.
Sandra, can you explain a bit more about what you need and what it will be used for!

Concerning copper photo etching - this technology is well used all over the world. As to stainless steel - we can develop for you technological processes. We have developed passive photo-etching process for titanium without hydrogen emission.
Can anyone tell me what you need to do it on brass? In order to mass produce do I need any special equipment? Do we need special training? thank youChris Pildner
