Product name Laser Hardening

Application industry Automotive industry: stamping dies, injection molds, gearboxes; Mold industry: stamping dies, sealing forging dies, extrusion dies, injection molds, die-casting dies; Machinery: rails, bearings, gears; Metallurgy: rolling lines, saw blades, crane blades.

Features

• Non-contact scanning processing with rapid heating and cooling for high throughput and short lead times.
• Stable heat input and narrow heat-affected zone minimize distortion while improving surface microstructure hardness and reducing residual stress to enhance fatigue resistance.
• Flexible optical-path processing enables localized hardening without affecting adjacent areas; hardened layer thickness is controllable to optimize wear resistance.
• No surface damage after quenching and no need for secondary finishing; hardened layer is uniform and crack-free.
• Self-quenching of the matrix eliminates the need for quenching media; parts do not decarburize and material stability is preserved for repeatable quenching.
• Short thermal cycle and compact treatment area result in improved strength and fatigue performance.

Sample display
