Shell Molding Process VS Green Sand Casting

Shell molding process needs to use metal patterns, because the pre-coated resin sand needs to be baked at very high temperature in molding machines. So, its tooling cost is comparatively higher. Green sand casting process could use cheaper plastic patterns (also called as epoxy resin patterns), and aluminum patterns.
