Abstract: A method of assembling a mould for a wind turbine blade (20) includes providing a mould half (42, 44) having a mould shell (50, 54) with a first mould shell section (70, 80) and a second mould shell section (72, 82); positioning the shell sections and the at least second adjacent one another along an interface (74, 84); adjusting the relative positions of the shell sections, and securing the relative positions of the shell sections in order to maintain a smooth transition across the interface.

Abstract: A mold (30) for a wind turbine component (10) is described. The component comprises a plurality of elements having different respective heat capacities. The mold comprises an inner mold layer (38) defining a mold surface (40) for supporting the plurality of elements, heating means (44) disposed beneath the mold surface, and a heat distribution layer (46) adjacent to the heating means. The mold has one or more first regions (34) configured to support elements of the component having relatively high heat capacity, one or more second regions (36) configured to support elements of the component having relatively low heat capacity, and one or more transition regions (35) defined between the first and second regions. The heat distribution layer in one or more transition regions of the mold is configured to enhance heat transfer within the distribution layer to one or more first regions of the mold.
