Avoid pinholes, blowholes, and open holes by making sure the molding sand is dry and permeable. It should be noted that the coarser sand is, the more permeable it is. Even using sand that is too fine can prevent optimal permeability. Additionally, sand molds that have been rammed too much lose their permeability, so it's important not to overdo it. Make sure that molds and cores are dry ...
