Tool Identification That Lasts

Wire and Cable Marking vs. Stamping

For decades, hot wire stamping was the standard method for identifying wires and cables, using heat and pressure to transfer pigmented foil onto wire insulation. While still common, this approach limits durability and wire insulation integrity. Telesis Technologies, Inc. provides two complementary marking technologies, UV laser and dot peen, that address the complete spectrum of wire and cable identification needs. Together, these technologies deliver permanent, high-contrast identification without the limitations of traditional hot stamping.

Advantages of Modern Wire Marking Technologies

Modern UV laser and dot peen marking technologies deliver measurable advantages over traditional hot stamping methods:

  • Damage-free wire insulation marking: UV laser marking is a non-contact process that preserves the wire’s dielectric strength and integrity. Unlike hot stamping, which applies heat and pressure that can degrade insulation, UV lasers use a “cold marking” process that induces chemical color changes without thermal damage.
  • Superior mark quality and permanence: UV lasers produce high-resolution characters on wire insulation with precision beyond that achievable with hot stamping. Dot peen markers deliver deep, tactile marks on metal components that remain legible even when surface coatings wear away.
  • Unmatched flexibility and speed: Modern marking systems allow codes and variable data to be changed instantly via software. Both technologies integrate seamlessly into automated wire processing lines, significantly exceeding the marking speed of mechanical hot stamping.
  • Complete wire harness traceability: By combining UV laser marking for wire insulation with dot peen marking for metal terminals and connector housings, manufacturers achieve comprehensive identification throughout the entire wire harness assembly.

Marking Solutions for Wire and Cable Identification

Complete wire harness identification requires two complementary technologies. UV lasers mark wire insulation directly, while dot peen markers identify metal components and assemblies.

UV Laser Markers

UV laser markers are the premier choice for modern wire insulation identification. Their cold marking process safely marks sensitive insulation materials such as Teflon™ (PTFE), ETFE (Tefzel™) and Kapton™ (Polyimide film) without compromising their dielectric strength or causing micro-cracks.

UV lasers excel where hot stamping fails — marking thin-wall insulation without physical deformation, creating marks resistant to harsh solvents and hydraulic fluids, and enabling high-speed automated marking during production.

The UV/One™ is an ideal, compact solution from Telesis Technologies, Inc., engineered for easy integration into existing wire processing lines.

Dot Peen Markers

Complete wire harness identification requires marking metal components that support and organize the wiring system. PINSTAMP® dot peen markers provide robust, permanent identification for metal cable tags, terminal blocks, connector housings, junction box covers and ferrules.

Physical indentations remain legible even when surface coatings wear away. Marking metal terminals with unique identifiers enables rapid assembly verification and efficient troubleshooting. Dot peen markers create permanent 2D Data Matrix codes and serial numbers that withstand vibration, temperature cycling and chemical exposure.

The PINSTAMP® TMP1700 and portable TMP4500E models offer flexible solutions with floating pin technology that adapts to curved terminal surfaces and irregular connector geometries.

Applications for High-Performance Wire Identification

In aerospace and defense, UV laser marking provides damage-free identification on sensitive wire insulation materials, while dot peen markers create permanent identifiers on metal terminals and connector housings. This comprehensive identification enables efficient assembly and rapid repair while reducing weight.

The automotive and motorsport industries rely on precise wire identification for rapid assembly and long-term maintenance. UV laser marking ensures insulation identifiers remain resistant to extreme temperatures and fluids, while dot peen marks on metal terminals withstand abrasion and chemical exposure throughout the vehicle’s lifespan.

In complex electrical systems and control panels, UV laser marking allows for high-density marking on wires, while dot peen marking identifies junction boxes and terminal blocks, preventing misconnections and ensuring safe operation.
