At JEC World 2025, the leading international composites show held in Paris from March 4-6, CANNON Legos, a company of The Cannon Group, showcases an innovative, fully automatic system for the in-line vacuum degassing of resins for the production of large composite components using vacuum infusion, RTM and pultrusion. The new system combines a compact design and footprint, offering high output and significantly reduced processing times.
“We started developing this technology based on the requirements for the wind energy market. As the sector moves to ever larger wind blades for bigger power generation, there is a strong demand for greater outputs without compromising performances and costs,” explains Davide Bertinat, Product Manager at CANNON Legos. “The technology we developed is building on the vast experience that Cannon has in the oil & gas sector, particularly for water treatment on offshore platforms. This was then adapted and customized for resin degassing and, after a period of testing and adjusting, we achieved the desired high in-line output, while maintaining a small footprint.”
At present, degassing technologies are mainly operated off-line in batches with low throughput and long processing times. Although some existing technologies are already aimed at in-line processes, these tend to have limited output. To bypass this, some suppliers will offer more than one unit to cover higher volumes. The innovative solution from CANNON Legos drastically reduces the overall degassing time, processing one cubic meter (1 m3) intermediate bulk container (IBC) in less than 10 minutes. This solution enhances efficiency and ensures an optimized footprint, even at the high output rates.
Moreover, a single CANNON unit can replace several existing modules, allowing customers full integration in production processes thereby saving operating costs, time and space. Several major wind turbine manufacturers have already indicated their interest in our innovative system in response to their need for a significant increase in the volumes of chemicals needed for wind blades production.
