A process for the production of a crank lever for a bicycle, comprising the steps of: providing moulding equipment (20) including two mobile half-moulds (22, 24) which move between an open position and a closed position, in which the equipment (20) in the closed position defines a moulding cavity (26) having a shape corresponding to that of the crank lever to be produced; introducing into the moulding equipment (20) in the open position at least one insert and a pre-set quantity of fibre-reinforced thermosetting material in a plastic state; closing the moulding equipment (20) and applying to the aforesaid thermosetting material (48) a pressure via the surfaces (30, 32) of said moulding cavity (26) so as to cause the material (48) in the plastic state to flow into said moulding cavity (26) so that this material fills the moulding cavity (26) and covers at least partially the aforesaid insert (44, 46); and heating the aforesaid thermosetting material (48) up to a thermosetting temperature. <IMAGE> |
