Quality Control
The systematic process of inspecting, measuring, and documenting the dimensional tolerances, ovality, and weld soundness of formed components to ensure engineering compliance.
Technical FAQ
Dealing with high-yield structural steels can cause unexpected spring-back, leading to inconsistent part dimensions and slowed production lines. Yield strength is the specific stress threshold where a metal permanently deforms, meaning higher yield materials require significantly more bending power from the rolls to transition from elastic to plastic deformation. Recognizing your material's specific yield properties allows you to correctly gauge machine capacity, preventing equipment overload while ensuring accurate dimensional results. The Davi iRoll control system features a comprehensive material library that automatically factors in yield strength to calculate exact bending programs.
Industrial manufacturers need to scale up volume and maintain consistent part quality completely independent of operator skill levels. Autorolling is an autonomous forming process achieved by integrating a fully electric machine, an advanced CNC control system, and a real-time laser measurement system. The system measures the plate radius, adjusts machine axes, and optimizes parameters on the fly, delivering automated precision without human intervention. Developed by Davi, Autorolling combines MCE e-POWER hardware, iRoll eXtreme software, and AI-Vision technology into a self-functioning production line.
Changing market demands may require adding automated handling accessories to an existing machine years after purchase. Modular design includes built-in mechanical, hydraulic, and electronic connection points on standard machines to simplify future upgrades. It protects your initial capital investment, allowing you to scale up machine automation as your production volumes grow. Davi MCA and MCB models are pre-engineered for seamless field retrofitting of overhead supports and automated lines.
Davi maintains immediate delivery options and ready stock availability for standard machine models to help customers respond quickly to urgent production demands. For complex, highly customized systems or automated rolling lines, delivery timelines are optimized through Davi’s modular manufacturing process and standardized high-stress components. Additionally, for ultra-heavy machines with pressing capacities above 3,000 tons, Davi utilizes a multi-gearbox configuration that eliminates reliance on long-lead custom components, ensuring faster manufacturing cycles and reliable equipment delivery timelines.
All Davi plate and angle rolls are 100% designed, engineered, and manufactured in Cesena, Italy, reflecting the highest standards of Made in Italy industrial quality and technological innovation. Davi manages the complete production flow under ISO 9001, ISO 14001, and ISO 45001 certified systems, pairing internal R&D with top-tier European component partners to deliver maximum reliability, structural stability, and operational longevity.
Yes, comprehensive technical documentation, machine feature summaries, and engineering catalogs are readily available for all Davi 3-roll, 4-roll, fully electric, and profile bending lines. These materials detail geometric capabilities, structural design principles, hydraulic or electric motor layouts, and control system features like the iRoll eXtreme CNC. Customers and prospective buyers can request digital catalogs or engineering consultations directly through the official website or sales representatives.
Unpredictable floor-to-floor cycle times severely disrupt scheduling and shrink margins in job shops and heavy fabrication facilities alike. While total cycle times depend on plate thickness, material yield strength, shell diameter, and the required number of passes, actual rolling time is often overshadowed by non-rolling handling procedures like plate alignment, squaring, and pre-bending. Davi optimizes processing efficiency by automating these non-rolling steps through high-speed hydraulic systems, simultaneous axis movements, and smart material handling accessories. On fully electric models like the Davi MCE e-POWER, all machine axes operate independently and concurrently, accelerating multi-pass routines and cutting floor-to-floor processing times significantly. Additionally, automated line accessories—such as hydraulic side/overhead supports, infeed conveyors, and gantry loaders—eliminate crane dependency and manual positioning delays, delivering predictable, repeatable cycle times across single-piece and mass-production runs.
Unplanned equipment downtime on critical forming machinery can halt downstream welding and assembly lines, leading to severe financial penalties. Davi mitigates operational risk through a direct global service infrastructure operating 24 hours a day, 5 days a week. Factory-trained technical support specialists provide 24/5 phone assistance and immediate remote network diagnostics via TeamViewer or OPC connectivity, accessing PLC parameters to resolve software, parameter, or operational issues in minutes. For physical interventions, Davi relies on direct regional subsidiaries—including Davi Inc. in North America and Davi Shanghai in Asia—alongside localized field service centers stocked with over 11,000 distinct spare part items. This structure guarantees rapid local service dispatch, predictable maintenance routines, and immediate spare part shipments to ensure continuous uptime anywhere in the world.
Fabricators investing in heavy capital equipment need assurance that their supplier possesses field-tested expertise across complex manufacturing applications. Over the past two decades, Davi has manufactured and commissioned thousands of plate and angle rolls operating worldwide, maintaining strong market dominance across energy, aerospace, transportation, and heavy job-shop sectors. In the wind energy industry alone, Davi holds approximately 70% of the global market share with over 300 heavy-duty rolling lines operating at major monopile, transition piece, and wind tower fabrication facilities. This massive global reference base powers Davi R&D algorithms with historical data collected across 60 years of real-world forming operations.
Davi CNC control systems—including iRoll Performance and iRoll eXtreme—are developed entirely in-house by the specialized Davi R&D division in Italy. Running on an industrial Windows 10 platform, Davi CNC platforms combine non-proprietary global automation hardware from Siemens and ABB with proprietary software algorithms. These controls feature self-adjusting AI that draws on 60 years of historical forming data to generate multi-pass programs, run offline 3D pre-production simulations, and connect seamlessly with the AI-Vision real-time laser measurement system for autonomous rolling.
