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

• 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
