Whenever repeatability, productivity and ease of use are of essence, the 4-roll is the technology of choice. In a 4-roll machine, latest development of the rolling technology, the bottom roll clamps the plate guaranteeing a perfect control over its position throughout the whole forming process. The side rolls, actuated by the unique DAVI planetary guides technology, provide the necessary bending force achieving the tightest diameters per capacity on the market (1.1 of the top-roll) obtaining the highest accuracy thanks to the perfect parallelism offered by the patented Servo-Tronic© system. Compared to other technologies, 4-roll machines stand out for allowing fully CNC-automated production processes, significantly decreasing the reliance on operators’ skills and, hence, making it the most suitable tech for mass-production.
The Davi MCA 4-roll system is the latest in rolling technology. The bottom roll clamps the plate for precise positioning throughout forming, while the side rolls, driven by DAVI’s unique planetary guides, deliver the bending force needed to achieve the tightest diameters
UK defence spending is rising at a pace not seen since the Cold War, and for metal fabricators with the right capabilities, that represents a significant commercial opportunity. Understanding where the demand is coming from, and what it means for workshop investment, is worth the attention of any fabrication business looking to grow.

In recent years, the Health and Safety Executive (HSE) has placed welding fumes under closer scrutiny, with scientific evidence linking exposure to a range of health issues, including lung cancer, neurological disorders, and asthma. Employers have a duty to provide a safe and healthy working environment for their staff, which includes putting effective controls in place to manage exposure to welding fumes — general ventilation on its own is not enough to adequately mitigate the risks. Although welders themselves may be adequately protected by PPE, the HSE has placed particular emphasis on other employees who share the same workspace.

Net zero isn't just a government target, it's increasingly a commercial reality. More and more UK manufacturers are being asked by their customers to demonstrate their environmental credentials, and fabrication businesses that can't answer that question are starting to lose work to those that can.
