The Pattern Shop and the Materials Laboratory at the Puget Sound Naval Shipyard are now conducting a series of tests to develop and manufacture plastic foundry patterns that will justify their use both economically and technically. They do have their limitations, but when these are recognized and corrective measures taken in the manufacturing processes these limitations can well be overcome, thereby making some of the epoxy resins excellent pattern materials. Several methods have been developed to success fully cast the various types of patterns and coreboxes.
