Laser Hardening Equipment Series | Automated Laser Hardening System for Pliers Blades

This advanced laser hardening system utilizes cutting-edge lasers and industrial robots to achieve multi-axis synchronized automation processing. It can also be customized based on customer requirements, with tailored tooling and material handling systems for automatic laser hardening and loading/unloading functions. The laser hardening process offers high power density, rapid cooling, and eliminates the need for cooling media. The hardened layer is uniform, offering higher hardness with minimal workpiece deformation. It is easy to control the heating depth and path, making it ideal for surface treatment of high-precision components. Laser hardening is gradually replacing traditional induction hardening and chemical heat treatment processes, becoming the preferred choice in industrial applications.

Advantages of Laser Hardening Technology

Laser hardening is a process that uses a laser to heat the surface of the material above its austenite transformation point. The material then cools on its own, transforming austenite into martensite, thereby hardening the surface. Laser hardening features high power density, rapid cooling, and does not require cooling media like water or oil. Compared to induction hardening, flame hardening, and carburizing processes, laser hardening produces a uniform hardened layer with higher hardness, minimal workpiece deformation, and precise control over heating depth and path. It is easier to automate and does not require designing specific induction coils for different part sizes, as needed with induction hardening. Moreover, laser hardening does not face limitations from furnace size when working with large parts, unlike carburizing or other chemical heat treatment processes.

As a result, laser hardening is gradually replacing traditional heat treatment methods, including induction hardening and carburizing, across various industrial sectors. Notably, the deformation of workpieces before and after laser hardening is almost negligible, making it particularly suitable for surface treatments of high-precision components.
