KingVan Launches Dual-Laser Hybrid Marking System for Multi-Material Thermal Strips

July 2, 2026

JINAN, China – KingVan Technology has launched the KV-Hybrid-20, a dual-laser marking system that integrates a 20-watt UV laser and a 60-watt CO₂ laser in a single production station, enabling thermal break strip manufacturers to mark both white polyamide PA66 and fiber-reinforced GF25/GF30 profiles on the same production line without tooling changeovers. The system addresses a growing challenge for extruders who produce multiple strip formulations and need to maintain permanent, high-contrast markings across all material variants.

The thermal break window industry has seen a steady shift toward multi-material product portfolios as building codes in Europe and North America tighten thermal performance requirements. Window manufacturers increasingly specify different polyamide formulations for different profile families—standard PA66 for residential windows, glass-fiber-reinforced PA66 GF25 for heavy-duty commercial frames, and high-load PA66 GF30 for curtain wall systems. Each material presents different marking characteristics: UV lasers produce sharp, high-contrast black marks on GF25 and GF30 materials through a carbonization reaction, while white PA66 typically requires CO₂ laser energy for optimal readability.

"Until now, extruders producing multiple strip formulations had two choices: run separate production lines with dedicated laser marking systems, or accept suboptimal mark quality on certain materials by using a single laser type," said KingVan's head of product development. "The KV-Hybrid-20 eliminates that compromise entirely. The system automatically detects the material type via a spectral sensor and switches between UV and CO₂ laser sources within 200 milliseconds, so the production line continues running at full speed regardless of the strip formulation being fed."

Technical Architecture

The KV-Hybrid-20 integrates both laser sources into a single optical path using a precision dichroic beam combiner, which transmits UV wavelengths while reflecting CO₂ wavelengths onto the same galvo scanning head. This optical design ensures that both laser types share the same focal plane, marking field (110 mm × 110 mm), and Z-axis positioning, eliminating the need for separate optical alignment when switching between sources. The UV laser delivers a spot size of approximately 25 microns at the workpiece surface, providing sufficient resolution for Data Matrix codes as small as 3 mm × 3 mm with cell sizes down to 0.15 mm. The CO₂ laser operates with a 120-micron spot size optimized for the larger-character text and barcode marks typically required for white PA66 strip identification.

Both lasers are driven by a common control architecture running KingVan's proprietary MarkOS software. The control system stores per-material marking recipes that define laser type, power, scan speed, pulse frequency, and line spacing for each product SKU. When the material sensor detects a change in strip formulation—for example, the transition from black GF25 to white PA66—the system loads the appropriate recipe and switches laser sources automatically. The entire changeover takes place without pausing the conveyor feed, maintaining continuous throughput at speeds up to 40 meters per minute.

Shop-Floor Performance

In pilot production trials conducted at a major Chinese thermal strip manufacturing facility, the KV-Hybrid-20 demonstrated the following performance metrics across three common polyamide formulations:

The system maintained a production uptime of 98.2% over the four-week trial period, with the only scheduled downtime being weekly galvo mirror cleaning and laser source preventive maintenance. Consumable costs were limited to compressed air for the marker air knife and occasional isopropyl alcohol for optic cleaning—consistent with KingVan's zero-consumable UV and CO₂ marking architecture.

Market Positioning and Availability

The KV-Hybrid-20 is positioned as a mid-range production system, priced approximately 30% above KingVan's standard single-source single-traction marking system but with the capability to replace two separate single-source systems. KingVan estimates that a manufacturer producing three strip formulations across two production lines could achieve a return on investment within 14 months through equipment consolidation, reduced changeover downtime, and elimination of consumables associated with inkjet or mechanical marking alternatives.

First shipments of the KV-Hybrid-20 are scheduled for August 2026, with initial deliveries prioritized for customers in the European Union, Middle East, and Southeast Asia—key markets where multi-material thermal strip portfolios are most prevalent. KingVan will demonstrate the system at Fensterbau Frontale 2027 in Nuremberg, Germany, and at BAU 2027 in Munich, where the company expects to showcase the hybrid technology to European window profile extruders evaluating marking equipment upgrades.
