Abstract: In this mould, the sum of the areas of the cross-sections of the runners (30) in service is, at at least one casting instant, greater than the area of the cross-section of the casting pool (28), or at least of the same order as this area. This makes it possible to slow down the metal during its passage in the runners and thus to obtain non-turbulent filling of the impressions. <??>Application to the multi-stage moulding of thin-wall castings.
