Precision Parts - General Etching

Challenge

Meet the needs of clients who are searching for concepts and ideas on how to etch different depositions from a variety of surfaces and substrates.

 

Deposition

A variety of non-precious and precious metals.

 

Substrate

Steel, Stainless Steel, Plastic and Rubber Surfaces.

 

Results

We were able to utilize our new patented solution and some other resources to develop and customize a process. 

 

The components that we processed are precision parts that are used in the production of lighting bulbs.

 

The precision parts consisted of steel, stainless steel, plastic and rubber surfaces. The depositions were oxides and nitrides of niobium and silicon, which was all over the parts so it was not possible to dismantle the parts to perform mechanical cleaning.

 

And it was the steel surface that made this task almost impossible.

 

The chemicals that would work on the deposition would harm this surface instantly.

 

The stainless steel would stay intact for hours but then it would start to dissolve.

 

Since the deposition was thick, it was obvious that the parts needed to stay in the etching mix for days.

 

With these constraints, we got busy with R&D, so that we can come up with a novel technology. Since we were not able to protect the substrate by the etching mix itself, we needed to invent a surface protectant that would allow the etching agents to work on deposition, and preserve the substrate’s surface, at the same time.

 

Fortunately, our new technology was already available, so we could test it on the above-mentioned surfaces. Our experiments had proved that the surfaces stay unaffected even under the action of strongest etching agents.
