If you require parts with a high dimensional accuracy but perhaps not the volume to consider die casting, then shell moulding provides an ideal solution.
A shell mould is produced from a metal pattern and fine sand is baked on to create a thin walled and highly accurate shell. Two parts of the shell are formed, cope and drag, in the process and are closed and set with a resin glue.
This shell can then be filled in a similar way to the sand casting process
to produce castings in aluminium, brass, bronze and iron. The shells are non-recyclable but are made in a mechanised process on our Super Simplex dual moulding machine. This allows for a reasonably large volume of castings with a higher accuracy than normal sand casting to be made.
