The global wind power industry is rapidly expanding due to energy transition demands, with the wind turbine casting market projected to reach USD 6.37 billion by 2031. Manufacturing technologies are evolving toward smart, automated, and energy-efficient processes, integrating IoT and AI for improved efficiency. Leading firms like PAMA and Taiwan’s Rong Tian Precision Machinery have introduced large-scale boring and milling equipment, while quality inspection and surface treatment technologies continue to advance. The WeldCast project promotes modular welding to reduce costs. Taiwan must strengthen equipment partnerships to enhance competitiveness in the global wind energy supply chain.
