Wind power is one of the most promising renewable energy sources due to its global availability and the technical progress already made. This is also reflected in the development of wind power capacity, which is seeing double-digit annual growth across the globe. However, cost-efficient processes for manufacturing wind power plants are in greater demand than ever to enable further expansion and for competing with traditional energy resources.
For this purpose Covestro, one of the world leading companies in high performance polyurethane solutions, provided the leading wind turbine blade manufacturer Goldwindwith a special Baulé® infusion machine for processing its high performance polyurethane resin. Goldwind and Covestro achieved a major breakthrough with the development and production of a 64.2 m long polyurethane turbine blade.
“Covestro Elastomers developed a tailor-made Baulé® machine for the direct infusion of polyurethane rotor blades,” said Philippe Jeantin, Global Head of Machines Division, Business Segment Elastomers at Covestro. “We designed this machine to solve various challenges involved in this manufacturing process, e.g. process under vacuum, high volume casting and speed of resin infusion. This machine is therefore combining a very accurate dosing, a large variable output controlled by in-mold pressure and a real time data management to ensure a high quality direct infusion process for these large rotor blades.”
