LMG's electric roll upgrade

Zero Guesswork, Maximum Repeatability: How Leading Manufacturing Group Transformed Plate Bending with All-Electric Roll Technology
LMG's electric roll upgrade

Story overview

When LMG set out to upgrade their rolling capabilities to meet demanding heavy-plate fabrication standards, they turned to Davi for an all-electric, sustainable solution. By replacing traditional hydraulic operations with the fully electric Davi MCE e-POWER 4-roll machine equipped with the iRoll eXtreme CNC, LMG eliminated hydraulic fluid dependencies, improved overall energy efficiency, and achieved unmatched operational precision with zero test scrap.

The Challenge

LMG faced strict precision requirements and rising operational costs while aiming to reduce their carbon footprint. Traditional hydraulic bending systems posed risks of oil leaks, high energy consumption, and long setup times that relied heavily on operator expertise to avoid material waste.

The Solution

Davi provided the MCE e-POWER fully electric 4-roll plate bending machine, integrated with the iRoll eXtreme CNC control system. This system completely removes hydraulic control units, enabling direct servomotor actuation, automated real-time program adjustments, and seamless multi-axis synchronization.

The Results

65% Energy Savings

Drastically reduced power consumption by drawing energy only during active movement via the Start&Stop system.

Zero Scrap & Rework

The AI-driven iRoll eXtreme system delivers the target radius on the first pass, eliminating trial-and-error material waste.

40% Noise Reduction

Operates at a whisper-quiet 58 dB, creating a safer and quieter workshop environment.

Minimal Maintenance

Completely eliminates hydraulic oil degradation, filters, and piping, significantly decreasing downtime.

 

The Industrial Credibility: Proven Performance and Reliable Support

Within just two months of integrating the MCE e-POWER into their 7-day-a-week production cycle, LMG successfully optimized its high-mix output with zero downtime. This operational success is backed by Davi’s long-term service commitment: any technical or programming questions are resolved immediately via remote support from Davi's dedicated North American customer service hub in Texas].  LMG’s confidence in Davi technology has led them to expand their fleet further, ordering a custom 4 ft. (1,200 mm) all-electric plate roll to automate the fabrication of non-standard oval manways.  

That’s going to make a huge difference on particular projects we have
