ABSTRACT:
A method of manufacturing a fan from a plurality of fan blades (12), comprising the steps of: providing an injection moulding tool (30) which defines a fan hub section (14); assembling a predetermined number of preformed fan blades with the injection moulding so that inner ends (16) of said blades extend into moulding cavities (32) within the tool, injecting synthetic plastics material into the tool, and allowing the injected material to cool or cure to thereby form a moulded hub with the inner ends of the blades bonded therein.
