Chemical Etching

Millennium Signatures is a leader in quality electro-chemical etching equipment, accessories, and supplies. The following pages provide a wealth of information regarding Chemical Etching and demonstrate our superior competence in this field. Electro-Chemical Etching does not cause distortion, sharp indentations, or unbalance in delicate parts. This process is widely accepted as a modern and economical way to mark on conductive metal surfaces.CONTENTS

Chemical Etching Technique

Manufacturers who produce nearly anything from Fine Cutlery to Saw Blades and Aerospace Components prefer this method of permanently identifying their parts.

Stressless

Electro-Chemical Etching is most applicable where hardened, thin and delicate, or already assembled parts must be marked permanently. There is no external force required to make an indentation or mark. Simple, fast & safe, the Electro-Chemical Etching Process is actually the reverse of electro-plating. A low pulsating voltage, low amperage current is passed through the open aperture of a paper or fabric stencil. The polarity is reversed from that used for electro-plating. A permanent surface etch 0.0001” deep is easily made in less than one (1) second.

Deep Etching

In some industries such as Automotive or Aerospace, specifications call for DEEP ETCHING in applications where the marked surface of the part may experience some wear or the mark must be deep enough into the part to allow it to be clearly read once painted or anodized. Millennium Signatures Marking Systems produces heavy duty Power Units that are equipped with timers and current control features such as our Electronic Pulse Control or EPC feature combined with a higher output allowing marking results of potentially up to 0.010” or 0.012” deep depending on the material and techniques used.

Contrast

On most metals, you have the control to produce a clean professional looking mark in one of three (3) possible colours or contrasts, Black, White (Clear) or Grey.

Safe and Easy to Use

The Electro-Chemical Etching Process is so easy to use that users need no special skills or training to use effectively. It is so fast that most permanent surface markings are made in less than one (1) second. The low currents used are harmless so it is absolutely safe.

Ideal Applications Include:

  • Taps & Dies  
  • Nuclear ComponentsChemical Etching Sample
  • Turbine Blades
  • Special Drills
  • Saw Blades
  • Tubing
  • Carbide Tooling
  • Bearings
  • Gauges
  • Stainless Steel Parts
  • Surgical & Dental Instruments
  • Titanium Parts

Glass Etching and Automotive VIN IdentificationVin Etch Stencils

Chemical etching can also be applied to glass etching and VIN identification on automobiles.  We manufacture and supply paper stencil products designed for glass etching and the VIN etching process.  Our 9300 stencil imprinter is highly effective to cut these stencils for glass etching applications.

Sample Part Marking

If you have parts that you would like to mark, we would be happy to test mark them and put our experience to work for you. Stamping, Engraving & Laser Part Marking Services are also available. Please contact us for more information.
