Laser Hardening Solutions

Selectively harden wear-critical surfaces without distorting the core. Our Laser Transformation Hardening (LTH) delivers precise case depths, superior wear resistance, and a quench-free process — all in a single automated pass.

Key Process Points

KUKA robotic arm scans the laser beam over the component surface with precise speed and overlap control
Self-quenching process — rapid cooling through the bulk material eliminates need for oil or water quenching
Hardening depth of up to 1 mm achievable in a single pass
Applicable to Tool Steel, Alloy Steel, Carbon Steel, and Die Steel
Selective hardening possible — only the required surface zones are treated, leaving rest of component unaffected
Minimal component distortion compared to conventional flame or induction hardening

Typical Applications

Die and punch face hardening for stamping tools
Gear tooth flank hardening
Cam and crankshaft lobe hardening
Guide ways and machine tool sliding surfaces
Cutting edge hardening on press tools and blades

Notes : Surface hardness and depth depend on carbon content of the steel. Higher carbon steels (e.g., D2, H13 tool steels) achieve better hardness response. Post-process light grinding may be required.
