SHELL MOULDING

Our Shell Moulding Process

Shell mould casting works much like traditional sand casting because workers pour molten metal into a disposable mould. However, this method forms a hardened, thin-walled sand-resin shell rather than a heavy sand box.

First, our Super Simplex fully automatic machine applies a specialised sand-resin mix over a heated metal pattern. Next, we separate the cured resin shell from the pattern and assemble the final mould. Because the metal pattern survives the process, our foundry reuses it to produce thousands of identical shells.

We manufacture shell moulds in two standard sizes:

• 16″ x 12″ (405mm x 305mm)

• 16″ x 14″ (405mm x 355mm)

Consequently, this efficient method allows us to manufacture custom castings up to a maximum unit weight of 15kg.

Exceptional Accuracy

High dimensional accuracy stands out as the main advantage of shell moulding. In fact, our process easily achieves tight tolerances down to ±0.5mm. As a result, you save significant production costs by minimising the need for secondary machining and heavy surface grinding.
