  Which green sand properties should you control per molding …

  201739 · 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.
