Industrial production line for recycling thermoplastic polymers and composites into organosheet


Cetim (Nantes, France) is already well-known for its QSP (Quilted Stratum Process) for industrialized production (< 1-minute cycle time) of thermoplastic composite parts, and also for its QSD (Quilted Stratum Design) software which optimizes such parts, including how to reuse production scrap back into the part. Its third enabling technology is a modular production line for turning thermoplastic scrap with and without fiber reinforcement into organosheet panels that offer desirable properties and cost.

UK composites structure manufacturer continues to expand


Norco (Poole, Dorset, U.K.), a manufacturer of large composite structures and glass fiber reinforced polymer (GFRP) moldings, got its start building boats, including the Sunseeker luxury motor yacht. While the company continues in its core competency of producing large glass fiber reinforced composite structures, over time it has expanded to include a range of bespoke products under the Norco Composites arm of its company. As a whole, Norco manufactures products for a variety of markets including renewable energy, civil engineering, marine and aerospace.

Corrosion-resistant composite piping over the long haul

The safe and uninterrupted operation of its chlorine production plant in Bergen op Zoom, Netherlands, is the main priority for chemicals manufacturer SABIC (Riyadh, Saudi Arabia). The plant began operations in 1987 and processes chlorine gas, strong acids and alkalis at elevated temperatures, which are highly corrosive environments where steel pipes could fail in only a matter of months. To ensure maximum corrosion resistance and reliability, SABIC selected glass fiber-reinforced plastic (GRP) for critical pipes and equipment from the start, and materials and manufacturing improvements implemented over the years have increased the design life of the composite components to 20 years, so that they need to be replaced less frequently (scroll down for a side story on chlorine production).

“We want to make sure that chemicals like chlorine, hydrochloric acid and hydrogen remain inside an enclosed environment and are well contained,” states Thana Kammeijer, manager, chemical operations, for the SABIC chlorine unit. “At the same time, we do not want an equipment failure to interrupt the continuous operation of the chlorine unit, as this may affect the downstream processes on this site. Therefore, we closely follow the condition of all piping and equipment and take the right actions for preventive maintenance.”
