Abstract: A method for manufacturing a wind turbine blade including: arranging an upper mold on a lower wherein a dry fiber lay-up is arranged in the upper mold or in the upper mold and the lower mold, applying vacuum to a space between the upper and lower molds, and infusing the dry fiber lay-up in the upper and/or lower molds with resin through at least one upper resin inlet arranged at an upper portion of the upper mold. Having the at least one upper resin inlet of the upper mold improves the vacuum-assisted resin infusion. Resin provided through the at least one upper resin inlet has to be raised by a smaller height to reach the top of the mold. A resin flow of the resin provided through the at least one upper resin inlet is supported in a downward direction by the gravitational force.
