Power and Precision for Extreme Conditions

Q: How do Davi plate rolls handle high-strength, wear-resistant steels like Hardox® or Dillidur® without damaging the machinery?

Processing high-yield, wear-resistant materials for the mining and earthmoving sectors requires massive bending forces due to their extreme hardness and tight bending radii. To address this, Davi engineers plate rolls with a significantly higher nominal capacity than the actual plate thickness being processed; for instance, offering a nominal capacity of up to 100 mm (3.94 in) to safely and reliably roll wear-resistant plates up to 40 mm (1.57 in) thick. By utilizing forged, heat-treated, and certified Chromium-Molybdenum steel rolls, our machines withstand the intense stresses of heavy-duty fabrication, ensuring long-term reliability, precise dimensional tolerances, and maximum operator safety without structural fatigue.

Q: What solutions does Davi offer to prevent deformation when rolling long, thin plates for dump trailers?

Fabricating long, thin-gauge components for dump trailers—typically ranging from 3 mm (1/8 in) to 6 mm (1/4 in) in thickness and up to 8 m (26 ft) in width—presents a high risk of material sagging and deformation during the rolling cycle. Davi solves this challenge by equipping our plate rolls with dedicated overhead and side supports (up to 8 m / 26 ft long) that constantly stabilize the plate. This specialized handling system eliminates material flexing, guarantees precise curvature tolerances, and allows a single operator to safely manage the entire process, significantly boosting workshop productivity and reducing cycle times.

Q: Can Davi machines handle the heavy structural profiles required for mining and tunnel reinforcement?

Yes, Davi MCP section benders are specifically engineered to bend heavy structural profiles, such as H-beams, I-beams, and THN sections, which are essential for the reinforcement structures of mining and road tunnels. Powered by dedicated CNC software, these high-capacity, three-roll double-pinch machines achieve complex, variable multi-radius curvatures with extreme ease and repeatability. This automated control ensures consistent geometric accuracy across large production batches, reducing manual rework times and guaranteeing the structural integrity of safety-critical underground supports.

The mining and earthmoving sectors require rolling machinery capable of handling ultra-high resistance materials and complex geometries. Davi provides rolling solutions engineered to face the toughest challenges, ensuring reliability and constant performance in the production of critical components for the industry’s giants.
