A method for making a windmill blade is provided, whereby problems with glue joints and with exposure of the workers to environmentally hazardous substances are avoided. This is effected by making the windmill blade in a closed mold with a mold core () inside mold parts () for formation of a mold cavity (), in which fiber material () and core material () are placed. After applying vacuum to the mold cavity (), matrix material () is injected via a filling pipe (), which is placed at a downwardly oriented side edge of the blade during the filling. Hereby is established a flow front () which is used for indicating complete filling when this reaches the trailing edge of the blade and penetrates out through overflow apertures.
