Abstract: Manufacture of shaped bodies from fiber-reinforced plastics material, in which fibrous reinforcing material is positioned in a recess in a mould die (9, 10, 11) consisting of one or more parts. The die recess is then closed by means of a cover (12) which can move relative to the die, in order to form a mould cavity. A solidifiable, liquid plastics composition is introduced into the mould cavity and there subjected to a pressure of such magnitude as to substantially completely fill the cavity, the cavity then being held closed until the plastics composition has at least partially solidified. In order to reinforcing material to be used and in order to raise the mould capacity, the reinforcing material (4) is placed in the die recess while lying in prepared orientation in a thin-walled lining (1, 2) intended to be received in the die recess, the lining being removed, subsequent to a moulding operation, and replaced with a similar lining having fresh reinforcing material thereon.

Abstract: A mould part which is intended to be brought together with at least one other mould part, to form a closed mould cavity in which plastics objects can be shaped. The mould part comprises a composite mould body which includes a support section (10) made of rigid material and having a surface whose shape corresponds to the shape of the object to be formed, and a mould shell (2,3,4) which is detachably arranged on said surface and which is suitably made from a plastics material having an extremely fine surface which serves as the moulding surface. The mould shell can be readily replaced, at low cost, with a new mould shell, after having been in use for a given length of time. The invention also relates to a method for manufacturing mould parts in accordance with the above, and to the use of such mould parts.
