Our Shell Moulding Process

Shell mold casting is a process similar to sand casting, in that molten metal is poured into an expendable mold. However, in shell mold casting, the mold is a thin-walled shell created from applying a sand-resin mixture around a pattern using a Super Simplex fully-automatic machine. The pattern, a metal piece in the shape of the desired part, is reused to form multiple shell molds.

Our moulding “Shells” are 16″ x 12″ or 16″ x 14″.

Castings can be produced up to a maximum unit weight of 15kgs using this process.

Accuracy

Accuracy is the prime asset of Shell Moulding, therefore reducing the need for expensive machining and grinding operations. This is a more precise method of manufacturing castings and it is possible to achieve dimensional accuracy of +/- 0.5mm.
