Latest Patents

Sharman holds a patent for a "Method of casting using expendable patterns." This method involves locating an expendable pattern in a mould box, which has a gas permeable refractory coating. The process includes placing and compacting unbonded particulate material around the pattern and supplying molten metal into the box. This technique allows for the vaporization or burning away of the pattern, resulting in a defined shaped article while applying a vacuum during casting. The method is further improved by compacting the particulate material to a maximum bulk density where it contacts the coated pattern. This innovation reduces the risk of mould collapse, metal breakout, and pollution.
