Abstract (en)
[origin: EP0803303A1] The method of the present invention includes pre-compressing molding sand in a mold space at the lower part of it near the outer and inner side surfaces of a pattern and the inner side surfaces of a flask, where it tends to be not well consolidated, by inserting a thin-plate body into the molding sand. The method also includes pre-compacting the molding sand or consolidating all the molding sand. <IMAGE>
