Cable Marking Methods

Methods of marking a wire continue to evolve as technology advances. Different methods are being introduced to counterpart existing processing techniques. The outcome is a wide range of processing options to meet virtually all applications and production volumes. Marking wire with a unique and identifying number or character is a necessary part of wire assembly for long time. Most electrical standards require a mark identifying a specific electrical circuit for traceability in assembly and service.

To create precise, lasting, and spotless mark on cable assemblies, succeeding methods have been used.

  1. Ink-jet

This method is widely used, it is reliable, durable, easier and faster. Benefits are uncountable when it comes to ink jet marking. The ink jet is compatible to most of the wire insulation, and promises enduring and abrasion resistant marking.

  1. Laser Marking

Laser marking is an emerging marking technology, slower than ink jet but best suited for continuous marking. There are numerous advantages of laser marking, this is method superior to other labelling methods. It helps in creating the desired marks without damaging the work piece. The method is extremely fast and can create permanent, crisp, highly detailed mark on cable assemblies with any type of insulation.

  1. Hot Stamping

It is the oldest method, but still used to label individual wires in the cable assembly. With the help of specially designed heated equipment it is done. The advantages of the method comprise of, low cost and the ability to create permanent and legible marks in less time.

  1. Heat Shrink

This method is mainly chosen for its ability to create high contrast marks on to both stationary as well as rolling wires. The heat shrink tube is marked and cut to length on a dedicated machine.  The marked heat shrink tube is applied to the wire using the Judco Focus Lite or heat gun and it is applied using either of hot stamp or ink jet methods.
