Chemical Etching: A Tour Through The Process (3D Animation)

Chemical Etching is a subtractive manufacturing process that uses baths of temperature-regulated etching chemicals to selectively remove material to produce high precision metal parts in any desired shape. It is also referred to as Chemical Milling, Photo (Chemical) Etching, Electrochemical Etching, Photo (Chemical) Milling, Photo Chemical Machining, and Industrial Etching. The process is ideally suited to a wide range of materials. Most commonly used materials include stainless steel, non-, low-alloy steel, nickel, copper, bronze, brass, etc. Many other types of metal, e.g. gold, silver, aluminum, hastelloy, titanium, and special alloys such as nitinol and vitrovac, can be etched under appropriate conditions.

Widely used across a range of high technology industries, Chemical Etching could be the answer to your precision metal part needs. Complex, stress-free, burr-free components can be produced from your ideas into reality in a matter of days. Think how that could revolutionize your prototyping concepts. Now realize that this can be achieved on an industrial manufacturing scale as well, and as easily as your conceptual ideas.

Thanks🙏
It actually gave clear idea about the process...

Which chemical to use in etching plz tel me sir

Its a slow process not suited for high volume or unreactive metals. There is another way it involves stacking many layers of very thin material with an adhesive, pressing the stack, then either stamping or punching the blank then heating it to release the adhesive. I have made parts from .0005" 1100 aluminum and .001" copper. The parts will not be as accurate the tolerance is limited to about .002" but if its good enough its much faster.

If you try to cut that stack with a laser you will just start a fire we had an aluminum fire trying that.
