The Challenge

Bending heavy plate and thick steel sections often causes machine frame deflection, leading to flat ends and unwanted barrel shapes. Traditional manual "sweep checks" using templates rely on guesswork, causing severe bottlenecks, wasted material, and high labor costs that limit production capacity.

The Solution

Hammer Haag transformed its operations by combining two advanced, Industry 4.0-ready Davi technologies featuring automated iRoll CNC controls: the MCB 4-Roll Plate Roll for maximum clamping precision, and the MCP Double-Pinch Angle Roll for seamless beam and profile bending.

The Results

Instant CNC Automation

Saved bending programs eliminate manual template checking and dramatically speed up cycle times.

Flawless Fit-Up & Zero Waste

Maximum torque transmission delivers the shortest flat ends, ensuring precise downstream welding with no test scrap.

Universal Tooling Versatility

Quickly switch between flats, rounds, angles, and heavy beams without costly, time-consuming tool changes.

Bridges the Skilled Labor Gap

Intuitive touch-screen interface allows newer operators to execute complex rolling cycles with ease.

The Industrial Credibility: Over 50 Years of Engineering Stability

Davi’s high-mix fabrication technology is backed by more than 50 years of continuous R&D and dedicated vertical industry expertise. Every heavy-duty machine is designed and manufactured under strict quality standards (ISO 9001, ISO 14001, ISO 45001) in Cesena, Italy, utilizing premium, commercially sourceable components to guarantee maximum uptime. To ensure long-term manufacturing continuity, our customer service structure provides dedicated engineering support, 24/5 remote assistance via secure network access, and rapid spare parts shipping from a stock inventory exceeding 11,000 line items.

With higher quality top-of-the-line equipment, we gain the exibility to handle a wider range of work. Yes, we can roll thinner gauge material if needed, but our goal is to accommodate the big stuff
