Shell molding is a precision casting process widely used for producing high-quality iron castings (such as gray iron, ductile iron, and compacted graphite iron) with excellent surface finish and dimensional accuracy. The coated sand is heated and filled into the mold to form a casting, and then the molten iron is poured and cooled to get the casting. Production process:
Pattern Preparation→Sand Coating→Mold Formation→Curing→Mold Assembly→Pouring→Cooling & Shakeout.
