Metal Etching Services

  • Electro Chemical Etching / Electro Etching / Electrolytic Etching on Metal Services

    Description of Electro Chemical Etching / Electro Etching / Electrolytic Etching Part Marking Services:
    Electro Chemical Etching (also referred to as Electro Etching, Chemical Etching, Electro Marking, or Electrolytic Etching) is the operation of pressing an electrolyte-soaked electrode onto a stencil that is placed over a metal part. The electric current from the electrode dissolves the metal material under the stencil, thus creating the desired mark. The depth of the electro chemically etched mark will increase based on the length of time the electrode is pressed through the stencil onto the metal part.

    Advantages of Electro Chemical Etching / Electro Etching / Electrolytic Etching Part Marking Services:

    • No stress levied on the part being chemically etched / electroetched
    • Can easily burn through heat treated material (over 60 Rockwell)
    • Does not weaken the physical or chemical properties of the metal part
    • Low setup cost and low per unit charge for surface electro etching
    • Very sharp and crisp edges on chemically etched marks at depths up to 0.006"

    Features of Universal Metal Marking's Electro Chemical Etching / Electro Etching / Electrolytic Etching Part Marking Services:

    Electro Etching was used to etch 1mm high characters onto this 20mm diameter bearing race. A unique electroltic etching procedure was engineering by Universal Metal Marking for this high-run application.  Laser Etching could have been a good alternative, offering crisp, legible detail with these small characters, however, electrolytic etching was elected due to low cost of operation and exceptionally high production rates, which yielded a substantial savings to the customer.

    Electro Etching was utilized to etch Serial Numbers and Manufacturing Numbers 0.006" deep into these metal parts per Marking Specification MIL-STD-130. This part marking specification allows for various types of marking in the Aerospace and Military industries including Electrolytic Etching, Laser Etching, Laser Engraving, Metal Impression Stamping, Vibro Peening and more.  While many marking methods are acceptable by Spec MIL-STD-130, not all are equal in quality or in economics.

    Electro Etching was utilized to etch this logo 0.006" deep into heat treated tool steel part. The tool steel is heat treated to 58 - 60 Rockwell "C" scale. This 1st article test part exceeded customer’s production requirements by more than 300 percent. Standard electrolytic etching services could not achieve the required depth while maintaining a crisp sharp image. Standard engraving methods could not maintain the sharp points within this logo. Traditional cutting tools could not economically cut the heat treated steel. Universal Metal Marking Co. has developed a system that will maintain crisp legible logos at .006" deep.
