<p>A method and an apparatus are serving for manufacturing a sand mold for pouring a metallic melt of e.g. cast iron. A pattern (7) having a configuration complementary to the castings wished to be cast, forms an imprint in a volume of molding sand (5), as the molding sand during this is acted upon by both a static pressure from a squeeze plate (9) and by ultrasound from an ultrasonic generator (8). In the sand mold can be cast castings with fewer fins and a more even and smoother surface than known per se.</p> |
