ABSTRACT:
A casting pattern and process for producing a hollow casting. The casting pattern has a foamed material body and can be constructed to prevent seams or fins from forming at points which are accessible only with difficulty, such as inside points. The contour of the foamed material body is covered on one side with a refractory mold part which is to be molded into the produced casting to form a corresponding part of the contour of the produced casting.
