Automated Robot Laser Hardening System for Automotive Molds and Large Steel Components
Presentation of the equipment's characteristics
The GSTLH6000 Automatic Laser Hardening System is an advanced industrial laser surface heat treatment solution designed for high-precision hardening of automotive molds, forging dies, casting molds, steel components, shafts, guide rails, and other large metal workpieces.
The system integrates a high-power fiber laser, industrial robot, precision linear slide, intelligent motion control system, laser hardening optics, automatic process software, water cooling unit, and industrial electrical control cabinet into a complete automated production platform.
Through highly accurate laser energy control, only the target surface is rapidly heated above the transformation temperature while the substrate remains minimally affected. Self-quenching by the base material produces a hardened martensitic layer with excellent wear resistance, fatigue strength, and dimensional stability.
Compared with conventional flame hardening and induction hardening, laser hardening offers significantly lower thermal distortion, higher processing accuracy, better repeatability, reduced post-machining, and flexible automation for complex 3D surfaces.
GSTLH6000 is suitable for both new component manufacturing and remanufacturing applications, supporting continuous industrial production with stable quality, intelligent programming, and high production efficiency.
High-Efficiency Non-Contact Heat Treatment
Laser energy is precisely focused onto the target area, enabling rapid localized hardening without physical tool contact, minimizing deformation and preserving part accuracy.
Intelligent Multi-Axis Robot Automation
The integrated industrial robot and precision linear slide provide flexible multi-axis motion for complex curved surfaces, deep cavities, large molds, and oversized components.
Precise Process Parameter Control
Laser power, spot size, scanning speed, focal position, overlap ratio, gas flow, and scanning path can all be digitally programmed for consistent and repeatable processing results.
Minimal Heat-Affected Zone
Localized heating significantly reduces thermal stress and distortion while maintaining excellent dimensional stability and minimizing subsequent finishing operations.
Uniform Hardening Quality
Optimized laser optics produce consistent hardening depth and hardness distribution across large processing areas with smooth surface appearance.
Flexible Programming
Offline programming and CAD/CAM path generation enable rapid setup for different workpieces while reducing operator dependence.
Low Operating Cost
No electrodes, induction coils, or flame consumables are required. The process consumes minimal auxiliary materials while offering high energy efficiency and long equipment service life.
Continuous Industrial Production
Designed for 24/7 industrial operation, the system provides stable processing quality, reliable automation, and low maintenance requirements for mass production environments.
Wide Material Compatibility
Suitable for numerous ferrous materials including carbon steels, alloy steels, tool steels, cast steels, cast irons, and various die steels commonly used in heavy industries.
Easy Integration
The system can operate as a standalone workstation or be integrated into existing automated production lines, robotic manufacturing cells, and Industry 4.0 smart factory environments.
