Wax Removal

pressure vesselOnce the shell has been completed the wax has to be removed to create a hollow negative cavity in which to pour the molten metal. 

This is achieved by placing the shell in a steam pressure vessel (above) for 5-20 minutes where high pressure super heated steam melts and forces the wax from the mould. Melted wax is collected and recycled for use as new pattern tree runners.
