US5126089A - Method for easy removal of sand cores from ...

Sand cores are removed from metal or plastic coatings by exposing the cores to a humid atmosphere for a sufficient time to weaken the binder of the sand cores. The sand is then shaken from the casting. Metal or plastic castings with hollow passages are produced by forming a casting around the sand core bound with a suitable binder followed by exposing the casting
