Large-format sand molds for metal casting • Mold measurements up to 4 x 2 x 1 m • Does away with elaborate and expensive mold set-ups • Surface quality can be adjusted through use of different sands • Short throughput time (a few days) • Coarse-grained sands for high gas permeability • Sand molds correspond 1:1 with CAD model • Considerable flexibility with changes in geometry, • Structures can be designed in accordance with without additional expenses requirements, without having to watch for draft angles • No storage or maintenance of patterns • Cost savings particularly for complex molds and batch • Special sands prevent casting problems sizes of 1 to several hundred pieces Sand casting process 3.
