1. Laser Hardening – The Most Advanced Heat Treatment Solution Today
Laser Hardening is currently the most advanced surface heat treatment technology. It uses a highly controlled laser beam to heat specific areas on a component’s surface with exceptional precision. This technology is especially ideal for parts that require high surface hardness, complex shapes, and absolute dimensional accuracy – such as slide bars in linear motion systems.
2. Why Choose Laser Hardening for Slide Bars?
Slide bars often operate under high friction, continuous motion, and harsh industrial environments. Enhancing the surface hardness is a key factor in extending lifespan and maintaining operational performance.


3. Outstanding Advantages of Laser Hardening
✅ Surface hardness up to HRC 50–60
✅ Minimal distortion, no need for post-machining
✅ Precise heating on target areas
✅ No impact on the core of the part
✅ Enhanced wear resistance and load capacity
✅ Suitable for complex geometries

4. Real-World Applications
Laser hardening for slide bars is widely used in:
- CNC machines, cutting machines, grinding machines
- Industrial robots and automation systems
- Linear drive systems
- Presses, stamping machines, and mold production lines
5. Versatile Applications Across Industries
- Precision Engineering
- Automotive & Motorcycles
- Mold Manufacturing
- Machine Building
- Industrial Automation
