KingVan Unveils High-Speed UV Laser Marking System for Polyamide Thermal Strip Production

June 11, 2026

JINAN, China – KingVan, a leading manufacturer of laser marking and processing equipment for the building materials industry, has launched a new ultraviolet (UV) laser marking system purpose-built for polyamide (PA66 GF25) thermal barrier strips used in energy-efficient aluminum windows. The new KV-UV15 system achieves continuous marking speeds of up to 150 pieces per minute with zero surface charring, addressing a longstanding challenge in marking glass-reinforced polyamide materials without compromising their mechanical properties.

"Polyamide thermal strips are notoriously difficult to mark with conventional fiber lasers because the material absorbs energy at 1064 nm unevenly, often resulting in surface melting, discoloration, or micro-cracking that weakens the strip's tensile strength," said Dr. Li Wei, Head of R&D at KingVan. "By switching to a 355 nm UV source with our proprietary beam homogenization optics, we can achieve a cold ablation effect that removes only the surface layer without any thermal damage to the underlying substrate."

Breaking the Speed Ceiling for Thermal Strip Marking

The KV-UV15 incorporates KingVan's latest high-speed galvanometer scanning system and a 15-watt pulsed UV laser source with a pulse repetition rate of up to 200 kHz. In field testing at a major Chinese thermal strip extrusion facility, the system demonstrated the ability to produce legible Data Matrix codes and alphanumeric batch identifiers at a sustained throughput of 150 pieces per minute—a 60% improvement over the previous generation of CO2 laser systems and a 200% improvement over conventional inkjet printing when factoring in the elimination of drying time.

The system's integrated vision alignment module automatically detects the position and orientation of each strip as it enters the marking zone, compensating for variations in strip length and feed alignment without requiring operator intervention. This is particularly valuable for manufacturers running multiple strip profiles on the same production line, as the KV-UV15 can switch between marking formats stored in its onboard library in under 200 milliseconds.

Reduced Operating Costs and Environmental Benefits

One of the most significant advantages of the new UV marking system is its dramatically reduced energy consumption. Compared to CO2 laser systems of equivalent marking speed, the KV-UV15 consumes 50% less electricity, drawing just 1.2 kW during continuous operation. Over a 24/7 production schedule, this translates to annual electricity savings of approximately $4,200 per machine at Chinese industrial electricity rates, with proportionally higher savings in European markets where energy costs are elevated.

Additionally, the UV laser marking process eliminates the need for consumables entirely. Inkjet printing systems for thermal strips typically require replacement ink cartridges every 2-3 weeks at production-scale volumes, costing on the order of $8,000-$12,000 per year per production line. The KV-UV15's zero-consumable design, combined with a laser source rated for 30,000 operating hours, offers a total cost of ownership that is considerably lower than any solvent-based marking alternative.

EN 14024 Compliance and Certification Readiness

All marking produced by the KV-UV15 meets the readability and durability requirements of EN 14024, the European standard for thermal barrier profiles. Test specimens subjected to 5,000 abrasion cycles and 1,000 hours of accelerated weathering (UV-A exposure at 60°C) showed no measurable degradation in barcode scan rates, with all Data Matrix symbols maintaining A-grade readability per ISO/IEC 15415. The system is currently undergoing CE certification and is expected to receive compliance clearance before the end of Q3 2026.

"We designed the KV-UV15 from the ground up as a thermal-strip-focused machine," added Dr. Li. "Our engineering team spent 18 months working directly with extrusion manufacturers to understand the specific pain points of their marking processes. The result is a system that doesn't just mark faster—it marks better, with less maintenance, lower power consumption, and no hazardous waste stream. That is what 'industry specific' should mean."

KingVan is now accepting pre-orders for the KV-UV15, with first deliveries scheduled for September 2026. The system will be showcased at the KingVan pavilion during the China International Aluminum Extrusion Expo (CIALEX) in Guangzhou this November.
