Metal Etching
Marking round items with the etching system
This is a basic demonstration taken from a very old video, showing the etching technique used to mark a round, stainless steel cup.
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 Read more »

Stencil used is a permanent stencil, mounted in a plastic cover, held manually and aligned "by eye".
Etching system used: MiniEtch EU80 (manual unit). More powerful units available:, EU300 CLASSIC
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. Read more »
Portable etch marking of large items
Trend's Metal Etching systems are not only suitable for etching small products, but also in a factory environment to etch products that are too large to be placed conveniently on a bench or worktable.
Typical scenario of large product etching
Surgical Instrument marking systems
Etching instruments is fast , neat and inexpensive. Trend's surgical instrument etchers can easily be used for safely marking or etching medical equipment. This asset identification technique meets the requirements of ASNZ4187. Read more »
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. Read more »
Semi-Automatic Etching Systems
Semi-Automatic systems are suitable for those products requiring medium to high volume part-marking. The basic system consists of a pneumatic piston, etching control unit and electrolyte dosing pump delivering the fluid to the markinghead.
The operator simply loads the part, presses a footswitch and the marking is automatically completed.
The 2 main models are the FlowEtch and the ModulMat Read more »
Manual Marking Units
Manual metal etching - the simple alternative
If your product needs high-quality permanent marking, but you cannot justify the expense of a laser-marking system, or dont need a semi-automatic ething system- then the manual metal-etching systems are the ideal solution for you. Read more »
