  • Method of making a mold
    Patent number: 4730657
    Abstract: Both a pattern member and a body of expansion material are covered with a layer of ceramic mold material. The body of expansion material has a coefficient of thermal expansion which is greater than the coefficient of thermal expansion of the ceramic mold material. The layer of ceramic mold material and the body of expansion material are heated. This results in a cracking of the layer of ceramic mold material by the body of expansion material due to greater thermal expansion of the body of expansion material as it is heated. During the step of heating the ceramic mold material and body of expansion material, the pattern member is melted to separate the pattern from the layer of ceramic mold material.
