Which green sand properties should you control per molding ...

Keep your green sand temperature below 120F ( 49°C ) from the mixer to the molding machine. In other words, your correlation between green sand properties will greatly suffer with high and variable sand temperature. Of course this requires you invest in a sand temperature control system, which will cool your sand because it's too hot.

What is Permeability? - Manufacturing Processes - 1

Pankaj -Posted on 26 Oct 15. - The property of moulding sand to allow gases to escape from mould is called as permeability. It is the ability of material or moulding sand to transmit gases. - Permeability of moulding sand decreases with increase in silt (soil or dirt) content of sand. - The density to which sand is rammed affects its permeability.

Ceramic Mold Casting - Manufacturing Process

The firing will burn off any unwanted material and make the mold hardened and rigid. The mold may also need to be baked in a furnace as well. The firing of the mold produces a network of microscopic cracks in the mold material. These cracks give the ceramic mold both good permeability and collapsibility for the metal casting process.
