Abstract: A method and apparatus for removing an item of shaped clay from a mould. The method including holding the piece (14) on a synthetic mould (10), pressing it against a resilient member (18) such that the member (18) substantially adopts the shape of the piece (14), and blowing the piece (14) off the mould (10), at which time the member (18) is compressed a little further to receive the clay (14) off the mould (10).

Abstract: An apparatus for manufacturing composite parts produced by resin transfer molding (RTM) is configured to operate in controlled flow-rate mode or controlled pressure mode to use the RTM technique for manufacturing large-sized composite parts with a low fiber content. In both modes, control is by means of a fuzzy logic control card. In controlled flow-rate mode the resin is injected alternately by two injection cylinders (40a and 40b) controlled by motors whose speed is controlled. In controlled pressure mode the resin is injected directly from resin supply vessels (16) subjected to pressure controlled by an air regulator (30).
