Global market valuation was derived through production capacity mapping and turbine installation volume analysis. The methodology included:
Identification of 50+ key casting manufacturers and foundries across North America, Europe, Asia-Pacific, and Latin America
Product mapping across ductile iron, gray iron, steel, and aluminum casting materials
Process segmentation analysis covering sand casting, investment casting, and die casting methodologies
Analysis of reported and modeled annual revenues specific to wind turbine casting portfolios
Coverage of manufacturers representing 75-80% of global market share in 2024
Extrapolation using bottom-up (turbine installation volume × casting weight per MW × material ASP by region) and top-down (foundry revenue validation) approaches to derive segment-specific valuations for onshore and offshore applications across small (<10 MW), medium (10-19 MW), and large (≥20 MW) turbine categories
