Greenstone GST Robotic Laser Quenching (Laser Hardening) System for Molds & Complex Curved Surfaces

Presentation of the equipment's characteristics

The Greenstone GST Robotic Laser Quenching System is an industrial laser hardening / laser surface quenching solution designed for high-value parts that require localized wear resistance, surface strengthening, and consistent heat-treatment quality. By combining a 6–8 axis linkage motion concept (robotic multi-axis operation) with a stable industrial integration platform, this system enables precise laser scanning and controlled heat input across mold steels and complex curved surfaces, where traditional flame/induction hardening may struggle with accessibility, distortion risk, or repeatability.

In real manufacturing and remanufacturing markets—especially tooling, die & mold, and complex mechanical components—customers demand repeatable hardness depth, minimal deformation, and high efficiency without heavy post-processing. The GST series supports a wide range of power configurations (3–12 kW) and adjustable processing coverage through selectable fiber cores and quenching optics, making it suitable for both small-area precision strengthening and larger-area surface treatment. The result is a modern laser-based hardening platform that improves part life, reduces unplanned downtime, and supports automated, standardized production.

• Multi-axis robotic linkage (6–8 axes) for complex geometries
The system is designed around a robotic multi-axis motion approach, enabling accurate path following on complex 3D contours, edges, fillets, grooves, and hard-to-reach regions typical in molds and formed components.

• Large-area processing capability for higher throughput
Built for industrial production, the GST robotic laser quenching solution supports large-area scanning coverage, helping users complete strengthening jobs faster compared with manual or segmented processes.

• Ideal for molds and complex curved-surface products
Optimized for surface quenching and strengthening on mold components and various complex curved-surface parts—enhancing wear resistance and extending service life.

• Stable industrial control architecture
Configured with Siemens S7-1500 electrical/control system for reliability, stable operation, and easier integration into factory automation environments.

• Flexible spot width for different hardening tasks
Selectable laser spot width (5–30 mm up to 5–60 mm) supports fine localized treatment or broader strengthening areas—matching real-world requirements from detailed edges to large faces.

• Robot + machine-tool integration concept
The motion platform is listed as “Robot + Machine Tool”, supporting robust industrial installation and accurate process execution for repeatable results.
