Marking Brass Handles - demo video

Video clip of electrochemical etching on brass handles. Part is held in place with basic bench-vice.

Grounding clip is attached to vice and part is marked. The electrochemical marking process takes about 2 seconds.

Electrolyte used: #639
Marking Time: About 2 seconds

Etching Brass Flanges - Demo Video

Video clip of sample etching on brass flanges. Part is not held in place but sits loosely, grounded via the stainless steel baseplate. Flange surface is cast, not machined, so some extra pressure could be used for a sharper finish, however no great difficulty was encountered in etching this sample.

Stencil used is a permanent stencil, mounted in a plastic cover, held manually and aligned "by eye".

Etching system used: MiniEtch EU80
Electrolyte used: #502
Marking Time: About 3 seconds

Setting up and marking with the MiniEtch EU80

The MiniEtch EU80 system is an electro-chemical metal etching system used to permanently mark metal products such as surgical instruments, drill bits or stainless steel products.

The marking process is very simple, simple connect the relevant leads, fasten some felt and contductive net and wet the marking head with some electrolyte. Now you can etch quantities of parts by simply pressing the marking head onto the stencil for a few seconds.

Electrochemical Electrolyte Solutions

Electrolytes are liquid solutions used to aid the electrochemical marking process.

Electrochemical etching is often incorrectly referred to as "acid etching" - however unlike "acid etching" - electrochemical electrolytes are not caustic and will not cause harm through incidental skin contact.
