Abstract (en)
[origin: WO0102146A1] A mould tool (10) for resin transfer moulding having a first member (11) defining a face mould surface (12) and a second member defining a contra mould surface wherein there is provided in at least one of members (11) for the mould surface (12) defined by the member; a channel (13) and an elastomeric member (18) located in and by the channel (13) defining in part a flexible wall (22) for the region; a pressurisible duct (17) extending through the elastomeric member (18); a passage (23) extending from the interior of the duct (17) to a location outside the mould member (11) whereby the pressure within the duct (17) can be varied to cause displacement of the flexible wall (22) between a first position (Figure 2) wherein the wall (22) is drawn inwardly to define and maintain a runner channel (24) in the mould surface of the member; and a second position wherein the wall (2) is released from forming the runner channel (24) and serves to provide a wall for the mould surface (12) of the member conforming substantially to that of the mould surface adjacent the channel (13).
