Precision rolling for residential and commercial electric boilers, ensuring uniform quality in every shell.
Systems like MCA, MCE, and MCB models are used to bend valves, water filtering devices, and ducting components with high accuracy.
Specialized "slim" overhead supports and reduced-diameter top rolls (e.g., 150 mm / 5.9 in or 190 mm / 7.48 in) allow for the production of narrow cylinders and small-diameter cans.

DATA
Material and thickness considerations for rolling applications.
Fully integrated systems that manage the entire process, from feeding to ejection, boosting productivity and cutting waste.
The first complete line of 100% electric plate rolls, offering unrivaled precision. This technology reduces energy consumption and minimizes the carbon footprint, aligning with modern sustainability goals.
Solutions designed for swift production cycles, accommodating various sizes and designs, typically with diameters ranging from 240 mm (9.45 in) to 720 mm (28.35 in).
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.
