Meanwhile, resin-coated sand is poured into the machine. Once the patterns have been heated, the press closes the two halves together and inverts the cradling, allowing for the sand to coat the pattern; at 200° F, the sand cures to form the shell mold, which is then ejected from the pattern. These molds can then be used for shell casting.

The more binder burned off the sand by the casting operation, the easier it will be for the re- claimer to operate at maximum efficiency. Sand is an excellent thermal insulator. It transfers heat at a surprisingly slow rate and establishes very wide thermal gradients in the resin-bonded sand core or mould.

How an epoxy resin coating works. An epoxy resin coating is a two-part product: a resin and a hardener. In this case, the resin is basically a clear synthetic polymer (a kind of plastic). It remains liquid until it's mixed with the hardener, and then it cures at air temperature until solid. The curing time varies.
