EHLA Laser Cladding – The process behind the precision
At Technoplating Group, we specialize in EHLA – Extreme High-Speed Laser Application – the most advanced form of laser cladding currently available. Unlike conventional laser cladding methods EHLA allows us to apply protective coatings with unmatched precision, thin layers, speed and efficiency. Whether it’s for new components or critical repair work, EHLA represents a new benchmark in surface treatment

What is EHLA Laser Cladding?
EHLA laser cladding is a cutting-edge surface treatment technology. The process involves using a high-powered laser to melt a thin layer of the base material while simultaneously introducing a metal powder into the laser beam. What makes EHLA unique is that the powder melts in the laser beam itself, before reaching the substrate.
This results in a metallurgical bond between the coating and base material — not a mechanical bond or adhesive layer, but a true fusion between the materials. This high-speed process creates a dense, pore-free coating that enhances the surface with properties like corrosion resistance, wear resistance and thermal shock resilience.
Key Technical Advantage: Extreme speed, minimal heat and thin layer thickness
Traditional laser cladding methods typically operate at speeds between 0.5 and 2 meters per minute. EHLA, by contrast achieves speeds of 50 to 500 meters per minute — making it up to 250 times faster. Despite this high speed, EHLA introduces minimal heat into the component. This significantly reduces the heat-affected zone, eliminates distortion and preserves the mechanical integrity of the base material. For precision-critical parts, this is a game-changer.
What’s more, EHLA enables the application of exceptionally thin and controlled coating layers, with thicknesses starting at 100 microns. This high level of precision makes EHLA ideal for applications where exact tolerances and minimal post-processing are essential.
New and Repair — One process for both
EHLA laser cladding is ideal for both new parts and repairs. Thanks to its low heat input and precise layer control, it can restore worn surfaces without affecting the base material — even on high-value or heat-sensitive components. Whether you're building new or extending the life of existing parts, EHLA delivers strong metallurgical bonding, minimal distortion and excellent wear and corrosion resistance. No setup changes needed — fast, efficient and sustainable.
From Honing to Cladding: Engineered for quality
What truly sets Technoplating Group apart is our ability to combine external honing and EHLA Laser Cladding — carried out entirely in-house.
Proper surface preparation is critical for laser cladding and external honing ensures each rod is perfectly straight, round and smooth before and after the coating is applied. This not only enhances the bonding of the clad layer but also guarantees superior final geometry and surface finish.
By uniting the strengths of our surface treatment divisions, we deliver a fully optimized, high-precision result that would be nearly impossible to replicate through separate suppliers. This synergy is the true strength of Technoplating Group.

Eco-Friendly and Sustainable
At Technoplating Group, environmental responsibility is embedded in every step of our process. Our EHLA laser cladding technology is generates less harmful emissions. Unlike traditional surface treatments, EHLA achieves up to 90% material efficiency — meaning almost all of the powder is applied directly to the product.
This significantly reduces waste and supports resource-conscious manufacturing.
As part of our commitment to sustainable operations, Technoplating Group works in accordance with ISO 14001 environmental management standards, ensuring compliance with strict environmental regulations and continuous improvement in environmental performance.
