I. Industry Background
Wire and cable are the lifelines of modern industry and infrastructure. Marking information such as cable models, specifications, voltage ratings, manufacturer details, and safety certification codes is not only a regulatory compliance requirement but also a critical basis for engineering installation, operation and maintenance management, and accident traceability. Incorrect cable identification can lead to engineering accidents with serious consequences. With the promotion of green manufacturing concepts and tightening environmental regulations, the limitations of traditional inkjet coding in the cable industry are becoming increasingly apparent, and laser marking is accelerating the replacement of conventional solutions.
Compliance and Labeling Requirements:
IEC 60228: Conductor cross-sectional area and specification marking; International Electrotechnical Commission standard.
UL/CSA Certification: North American market requires cables to bear certification marks, including certification numbers and rated voltage.
Chinese National Standard GB/T: Domestic cable marking specifications require complete information including model, manufacturer, and year of manufacture.
Fire-Resistant Cable Requirements: Mandatory identification including CCC certification numbers and fire-resistance ratings; markings must withstand high temperatures without peeling.
II. Pain Points of Traditional Marking Methods
High Consumable Costs for Inkjet Coding:
Solvents and inks are continuously consumed, requiring frequent maintenance and resulting in high long-term costs. For a medium-sized factory operating two shifts per month, consumable costs can reach several thousand RMB monthly.
Ink Prone to Fading Under High Temperatures:
During cable installation, cables are subjected to high temperatures, friction, and solvent exposure. Inkjet codes tend to fade or peel off, compromising subsequent operation and maintenance identification.
High-Speed Extrusion Production Lines:
Cables are continuously extruded at high speeds. Traditional printing methods struggle to maintain stable performance at such speeds, often resulting in broken or blurred codes.
Poor Flexibility for Content Changes:
Changing models or specifications requires equipment adjustments or plate changes, resulting in prolonged downtime and reduced production efficiency.
Environmental Pressures:
Solvent emissions and waste liquid disposal face increasingly stringent environmental regulatory requirements.
III. Typical Application Case
CO2 Laser Application in Premium Cables
The CO2 laser coding system applies laser marking of model, specification, and certification information on cable surfaces, delivering a distinctive gold-colored marking effect that adds a premium appearance and added value to the product. The system supports high-speed online integration and real-time content modification, meeting various compliance certification requirements including UL, CSA, and Chinese national standards.
