To meet the intensive throughput demands of the heating and ventilation sectors, Davi designs fully integrated automatic rolling lines that manage the entire fabrication cycle, from sheet feeding to finished cylinder ejection. By eliminating manual handling and operator-dependent variables, these automated systems dramatically reduce cycle times and consistently deliver highly repeatable parts. For high-volume applications such as water heaters, boilers, and air ducting, our technology easily accommodates fast-paced production cycles for diameters ranging from 240 mm (9.45 in) to 720 mm (28.35 in), helping manufacturers scale up capacity while maintaining strict dimensional tolerances.
Yes, our specialized systems are engineered precisely to protect delicate materials like stainless steel, aluminum, or pre-painted plates during high-precision forming. We equip our machines with hardened and ground rolls to prevent surface imperfections, and we offer advanced auxiliary accessories like motorized centering devices, side supports, and specialized "slim" overhead supports. For narrow cylinders and compact HVAC components, we utilize reduced-diameter top rolls of 150 mm (5.9 in) or 190 mm (7.48 in) to achieve tight, accurate bends down to the smallest diameters without sacrificing structural stability or parting tolerances.
The Davi MCE e-POWER represents the industry's first complete line of 100% fully electric plate rolls, engineered specifically to lower operational costs and support corporate ESG goals. By replacing traditional hydraulics with next-generation electric servomotors and a Start&Stop system, the machine only consumes energy when actively rolling, yielding up to a 65% reduction in electricity consumption. Additionally, removing the hydraulic unit eliminates the need for oil, filters, and complex piping, which slashes routine maintenance requirements, prevents environmental leaks, and reduces operational noise by 40% for a safer, quieter workshop floor.
Davi achieves zero-waste production by combining our intuitive iRoll eXtreme control system with the patented AI-Vision laser-based measurement technology. The AI-Vision system uses high-definition lasers to project thousands of measurement points across the plate, continuously reading the actual radius in real time and feeding this data back to the CNC program. The system automatically adjusts the rolls to correct for material variations, such as spring-back or batch-to-batch yield strength differences, ensuring the exact target radius is achieved from the very first run without the need for manual templates, test trials, or costly material scrap.
