Electric Plate Roll
A next-generation forming machine powered entirely by electric servomotors and actuators, eliminating hydraulic oil while delivering high precision and lower energy consumption.
Technical FAQ
Metal fabricators often need to diversify their production from flat sheets to structural profiles, which requires choosing the right technology to adapt to varying market demands. While plate rolling utilizes wide cylinders to form flat sheet metal into cylinders or cones, angle rolling utilizes specialized, narrower driven shafts to bend structural shapes like beams, pipes, channels, or angles. This clear distinction helps job shops select the exact machinery needed to maximize shop versatility, expand their service portfolio, and capture new commercial opportunities. Davi builds dedicated lines for both applications, engineering systems that handle plates up to 400 mm (15.75 inches) thick and structural sections like beams up to 1,200 mm (47.24 inches) in height.
Eliminating material waste and avoiding secondary cutting operations is a primary goal for high-productivity job shops looking to protect their margins. A flat end is the straight, unbent section left at the leading and trailing edges of a plate because the material cannot physically reach the exact tangent contact point between the machine rolls. Minimizing this straight section directly reduces material scrap and eliminates the time-consuming process of pre-bending plates on a separate press brake, thereby accelerating overall floor cycle times. Utilizing Davi all-rolls-drive technology ensures the plate can be positioned precisely at the tangent point to achieve the shortest flat end possible without compromising safety.
Mass-production facilities require automated processing with minimal reliance on highly skilled operator intervention to remain competitive. A 4-roll machine uses a top and bottom roll to securely pinch the plate, while two side rolls travel up to execute the bending force. It provides total material control throughout the cycle, allows for fully CNC-automated production lines, and makes the initial squaring process simple and safe. Davi MCA and MCB 4-roll lines are the global standard for high-productivity automation, offering rapid cycle times for job shops worldwide.
Modern manufacturers face strict ESG requirements and need to lower high workshop energy consumption. A fully electric plate roll replaces traditional hydraulic cylinders and control units with high-efficiency servomotors and next-generation electric actuators. It delivers up to 65% energy savings, eliminates hydraulic oil degradation, achieves 20 times higher positioning precision, and operates with a 40% noise reduction. Davi MCE e-POWER is the market's only complete line of fully electric plate rolls engineered for modern sustainable manufacturing.
Reducing idle energy waste during material loading and part inspection improves a plant's overall efficiency. The Start&Stop system cuts power consumption to absolute zero whenever the machine axes are not actively executing a movement. Unlike traditional hydraulic units that continuously draw power to maintain oil pressure, the machine absorbs energy only when performing work, lowering operational costs. This built-in green technology allows Davi MCE models to align with strict corporate sustainability goals.
Minimizing regular maintenance overhead and avoiding dangerous oil leaks keeps workshop production running continuously. Fully electric designs eliminate hydraulic pumps, extensive high-pressure piping, oil filters, and large reservoirs that degrade over time. Maintenance is simplified because the drive components are localized directly on the individual axes, reducing the need for regular fluid changes and checking for leaks. The Davi MCE series utilizes permanently lubricated components to drastically reduce scheduled maintenance overhead.
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.
Preventing collisions between massive workpieces and overhead supports protects your investment in capital machinery. The control system generates a high-resolution 3D simulation of the entire rolling sequence before the plate is loaded. It allows programming teams to spot potential tooling interference or material collisions offline, saving raw material and ensuring shop safety. Davi provides both on-console and offline simulation licenses for iRoll Performance and eXtreme platforms.
Waiting for an on-site technician during an unexpected software or operational issue can delay production schedules. Remote support allows factory-trained engineering teams to access the machine's PLC data securely over the network. It enables technical teams to diagnose faults, adjust parameters, and resolve programming issues in minutes without travel delays. Davi provides dedicated remote engineering support to minimize downtime and maintain production availability.
Deep foundation excavation can be expensive, disruptive, and complicated by high local water tables. A pit-free machine features a compact frame design that allows the equipment to be installed directly onto a standard reinforced workshop floor. It lowers initial installation costs, avoids expensive excavation work, and allows for faster machine setup after delivery. Davi designs its compact MCA 4-roll series to support pit-free installation layouts, helping job shops accelerate their return on investment.
