Foam Modeling and Tooling
Foam products are designed for tooling, modeling, foundry or mold patterns fabrication such as tooling board, polyurethane shapes or castable foams. These foam products need to have a fine structure, good strength, hydrostatic pressure resistance, and high machinability. Tooling applications can

The Effect of Process Characteristics on Metal Fill and Defect Formation in Aluminum Lost Foam castings
of foam patterns (low, medium, high), (2) coating permeability (low,. medium, high), foam tooling type (vented, ventless), (4) metal temperature (1200F, 1300F). The matrix. required a total 72 casting trials. The process responses include pour time, mold fill pattern via real time IR. imaging, and fold

Polystyrene
in the process are usually below 50 psi, allowing the use of relatively low-cost aluminum tooling. Unmodified polystyrene is rigid and brittle, has moderate strength, and is crystal clear. Impact strength is increased significantly by blending the polymer with rubbers such as polybutadiene. Heat

Low-pressure molding offers stiff competition
packing of the mold. Tooling costs may be 20 to 30% lower. Precise gas-injection and dynamic mixing produces foams with engineered cell structures that boost part strength and reduce weight. Manufacturing and assembly operations are eliminated -- components mold as one monolithic part. For large shot
