Abstract: A method for manufacturing a wind turbine blade, includes the steps of: arranging an upper mould including a pre-casted fibre lay-up on a lower mould comprising a dry fibre lay-up and a mould core, applying vacuum to a space between the upper and lower moulds and the mould core, infusing at least the dry fibre lay-up and a connection region between the dry fibre lay-up and the pre-casted fibre lay-up with a resin, and curing the resin. By having the pre-casted fibre lay-up in the upper mould, the packing and positioning of dry composite materials on top of the mould core is avoided.
