shell molding

Shell molding is a manufacturing process used to create metal parts with precision and fine surface finishes. It involves making a detailed, hollow shell mold by applying a binder-coated sand mixture onto a heated pattern, which forms a thin, durable shell. Once hardened, the shell is removed, and molten metal is poured into it, filling the intricate details. After cooling, the shell is broken away, revealing the cast metal part. This method combines the advantages of sand casting and investment casting, offering high accuracy, smooth surfaces, and suitability for complex geometries.
