Moulding flask is deformed by pressure of molten metal at casting, resulting in errors in the shape of the cast product. In this paper, three-dimensional deformation in six types of reinforcements (increase of frame thickness, crosspiece, edge bar, bottom plate, rib on frame, reinforcement of corner) for moulding flasks, is analyzed using FEM computer simulation. The maximum displacement of frame in each model under 0.098MPa pressure is measured, and stiffness per unit weight is investigated. The main results are as follows. (1) Every reinforcing method is effective. (2) The optimum reinforcing method for a netshape of castings, of eighteen calculated models, is that with triple cross pieces.
