    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.
