JK Series Housed Folded CO2 Laser Tubes

The JK series is an upgraded product based on the HK model. It enhances the high-voltage protection and adopts a fully dustproof and waterproof design, ensuring extremely high stability of the overall structure and preventing any changes in the mode.

The working medium has been optimized to achieve higher and more stable power, making it suitable for cutting applications on non-metallic and 3mm or thinner metallic materials.

Advanced 4J29 Kovar Alloy-to-Glass Sealing

Departing from conventional, deformation-prone structures, we utilize aerospace-grade 4J29 Kovar alloy. Through precise thermal-expansion matching technology, this structural design eliminates tube deformation and gas leakage, ensuring ultimate vacuum integrity and long-term mechanical stability.

Proprietary Discharge Tube Catalyst Coating

Our cutting-edge, internal catalytic coating technology efficiently regenerates CO2 molecules during the discharge process. This significantly mitigates gas degradation, guaranteeing an extended operational lifespan and remarkably stable power output over time.

Authentic UK GSI Gas Mixture & Premium Imported II-VI Optics

Empowered by a premier international supply chain, our tubes feature the authentic, specialized gas formulation from GSI (UK), paired with industry-standard, US-imported II-VI infrared optics. This combination ensures maximum beam transmissivity and minimal thermal distortion.

Unmatched Beam Quality & Rapid Response

Engineered for high-speed consistency, Hengkuai CO2 laser tubes deliver a rapid response time and exceptional unit-to-unit consistency. With an excellent TEM00 beam mode , superior power stability, and an industry-leading lifespan, our products are perfectly tailored for high-precision laser cutting, engraving, and marking systems.
