When you need to safely and permanently add identifying marks to wire and cable, ultraviolet (UV) lasers are hard to beat. The titanium dioxide typically found in white wire insulation reacts with the UV laser energy to make a black, high-contrast mark on the cable. Other colors of wire insulation can be marked using different chemical reactions. Depending on the insulation material, UV laser marks can be made to be smooth to the touch and extremely durable.

Lasers mark wire at high speeds on a variety of materials. Because they do not use inks or masks, there’s no waste. Laser wire marking is the gold standard for wire manufacturers in the following industries:

Aerospace. UV lasers are specified in aerospace industry standards as the preferred wavelength to mark white aerospace wires. The chemical interaction of the UV energy with the titanium dioxide does not penetrate too deep into the insulation and has been confirmed to have no effect on the performance of the wires.

Medical. Laser wire marking is clean and can be adapted to medical-grade cables.

Catheter marking. The process for marking catheters is similar to marking wires. Depending on the catheter material, smooth marks (not raised from the surface) can be achieved.

Other industries. Lasers are well-suited for a variety of other applications such as marking telecom/datacom, automotive, transportation, military and general electronics wires.
