Large-format sand molds for metal casting

Description

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