Cable and wire marking supports regulatory compliance, installation management, and lifecycle traceability across power, communication, automotive, and industrial applications. CIJ is the standard technology for continuous, high-speed in-line marking on extrusion lines. Two requirements are non-negotiable: meter marking must be continuous and accurate at defined intervals, or downstream cutting and installation go wrong; and the code must survive coiling, laying, friction, and outdoor weathering for the cable's whole service life.
