The result is a mold that can maintain better dimensional control over high production volume. b) "No Bake" molds replace the tradition clay-and-water or thermoset polymer binders used in traditional sand molds with fine wood chips. They are then compressed with high pressure without baking. c) "No Bake" molds replace the tradition clay-and-water or thermoset polymer binders used in traditional sand molds with dry clay that do not need heat in order to cure. The result is a mold that doesn't require and baking. d) "No Bake" molds is the same as the tradition clay-and-water but used in high production volume.arrow_forward
