.... Limitations The limitations of the evaporative foam casting method include: Each casting needs a pattern, and to pay for the pattern costs, the process depends heavily on saving in core costs. The patterns are weak and are liable to distort under compaction. The pattern bead density controls...

.... The pattern and polystyrene gating system are embedded in dry sand, and when poured, the polystyrene melts and evaporates. Cores are not required, and capital requirements are low. Dry sand is easily reclaimed compared to other processes. This process produces a clean, tightly toleranced casting. This process...
