The Challenge

Rolling long, thin plates for trailer bodies created critical bottlenecks for EXA Trailers: extended flat ends required tedious pre-bending on press brakes, friction-driven rolls slipped and misaligned plates, and shift-to-shift quality relied heavily on manual operator checks. To scale output, EXA needed a high-speed, repeatable rolling system that could streamline assembly.

The Solution

EXA deployed the Davi MCB 4-Roll Plate Bending Machine, engineered specifically for high-productivity shell rolling. Powered by planetary guides to minimize flat ends, permanent 4-roll clamping to prevent slippage, Servo-Tronic parallelism for perfect roundness, and automated iRoll controls, the MCB turned complex plate bending into a seamless, single-pass process.

The Results

Zero Rework & Shortest Flat Ends

Eliminated secondary pre-bending and edge-cutting, saving hours of manual labor per trailer.

30%+ Faster Cycle Times

Rolled and finished plates in a single continuous pass, accelerating delivery to downstream welding lines.

Flawless Fit-Up for Auto-Welding

Delivered precise cylinder geometry and tight seam alignment, enabling seamless, automated longitudinal welding.

Rapid Operator Onboarding

Intuitive iRoll console controls shortened the learning curve and maintained consistent shift-to-shift quality.

In the heavy-duty transport industry, manufacturing high-volume components like bulk material trailers, dry bulk tankers, and heavy-duty chassis requires an uncompromising balance of speed, structural integrity, and repeatability. Standard rolling methods often struggle to meet these demands, leading to bottlenecked assembly lines, material waste during pre-bending, and excessive manual correction.

This was the challenge faced by EXA Trailers Mexico, a leading manufacturer of specialized commercial trailers and owner of MCB. To maintain their competitive edge in international markets, they needed to dramatically accelerate their production of cylindrical and conical trailer bodies without sacrificing the strict geometric tolerances required for safe highway transport.
