Patterns for Shell Molding Casting

Shell mold casting is a metal casting process same as sand casting process, in this process molten metal is poured into an expendable mold. In shell mold casting, the mold is a thin-walled shell created from applying a sand-resin mixture over a pattern. The pattern, a metal piece in the shape of the desired part, is reused to form multiple shell molds.

These patterns contain whole Gating System on same Pattern Plate include Runner, Riser, Sprues, etc.

A reusable pattern allows for higher production rates, while the disposable molds enable complex geometries to be cast.
