<p>Resin transfer moulding equipment comprises a frame (1a-d, 6a-d), a first mould half (8) fixed within the frame, a second mould half (12) moveable relative to the frame, and means (50a-d) for moving the second mould half (12) into and out of a position in which the two mould halves (8,12) define a mould cavity into which resin may be injected. Each mould half comprises a shell (17,18) defining a mould surface and a support (9,11) for the shell which is sufficiently rigid to prevent deformation of the shell during the moulding process. Clamps (80) keep the mould halves closed during the moulding process. A plurality of lifting jacks (50a-d) for raising and lowering the second mould half (12) are connected together by a drive mechanism (60a-d, 70a-d, 65, 66, 62a-d, 68a-d and 73a-d) which transfers the movement of any one lifting jack (50) to the others. The lifting jacks are disengaged from the mould halves when the clamps (80) are operated.</p> |
