Industrial Laser System – Extreme High Speed Laser Deposition System
Extreme High-Speed Laser Cladding System
The EHLA Flexi system by ACUITY GmbH is a state-of-the-art, modular high-speed laser cladding solution built for the future of industrial surface engineering. Standing for Extreme High-Speed Laser Application (EHLA), this system delivers metallurgically bonded coatings at supersonic speeds – up to 100–500 m/min – drastically reducing processing times while ensuring superior wear, corrosion, and thermal protection.
Engineered in Germany and now available in India through United Spectrum Instruments, the EHLA Flexi system empowers manufacturers across sectors – automotive, defence, oil & gas, energy, aerospace, and heavy machinery – to transition from conventional thermal spraying or hard chrome plating to an environmentally sustainable and more efficient coating process.
Understanding Extreme High-Speed Laser Cladding System
EHLA (Extreme High-Speed Laser Cladding) is an advanced surface treatment technology that modifies the traditional laser cladding process by introducing:
- High scanning speeds (up to 500 m/min)
- Fine powder delivery close to the melt pool
- Low heat input, minimising distortion
- Thin layer coating of 25–300 μm with metallurgical bonding
This enables near-net-shape coating with minimal post-processing.
Unlike plasma spraying or HVOF, EHLA does not rely on adhesion-based techniques but instead produces diffusion-bonded coatings, resulting in superior performance under extreme wear and corrosion conditions.

FAQs
What makes EHLA different from traditional laser cladding?
EHLA uses high-speed scanning and close powder delivery, allowing thin, precise, and fast coatings with minimal thermal impact – unlike slow, bulky conventional laser cladding.
Can EHLA Flexi be integrated into my existing CNC or robot setup?
Yes. Its modular design supports integration with gantry systems, CNC turning/milling machines, or robotic arms with minimal retrofit.
What materials can be used with EHLA Flexi?
EHLA Flexi supports a wide range of metallic powders – Iron-based, Nickel-based, Cobalt-based, and tungsten carbide composites, depending on the application.
Is EHLA suitable for large or heavy components?
Yes. EHLA Flexi is often used to coat or repair large shafts, cylinders, and rollers with excellent throughput and coating consistency.
How thick are the coatings? Can I control the thickness?
Coatings range from 25 to 300 μm, depending on feed rate, laser parameters, and number of passes. Thickness can be precisely controlled.
