In addition to the standard shell moulding process, Vacuum Backed Shell Moulded castings offer all the benefits of the standard Shell Process with the ability to cast larger more complex castings up to 100Kg.

This process is based on the support of the shell moulds using the latest Vacuum Technology. Increased Rates of gas removal and very low fume emissions are also benefits of this Unique Process.

Below is the backing plant in operation. The shells are lowered and surrounded by sand. This is placed under a vacuum. The moulds are then filled with metal. On the right is an example of a large product produced on the backing plant.
