Low permeability of moulding sand leads to what defect

Answered by 987sumeetraj

The lower permeability is caused by finer grain size of the sand, high percentage of clay in mold mixture, and excessive moisture present in the mold. These are caused by liquid shrinkage occurring during the solidification of the casting.
