Lost Foam Sand Process

  • Lost foam sand casting process is a solid molding of a foam mold using a non-bonding agent dry sand combined with vacuuming technology.
  • The foam model similar in shape and shape of the casting is bonded and combined into a model cluster, which is coated with refractory paint and dried.
  • Vibrating modeling in dry quartz sand, casting under negative pressure, gasifying the model, liquid metal occupying the position of the model, and forming a new casting method after solidification and cooling.
