What is Lost Foam Casting Process?
Lost foam casting process, also known as full mold casting process is a new type casting method. In this casting process, the foam pattern that has same dimension with the casting will be first coated with refractory material and placed into quartz sand or forsterite sand after coating is dried. Then the sand will be compacted using a vibration table. Once compacted, the mold is ready to be poured at negative pressure. The melted metal will be directly poured into the foam-filled mold, burning out the foam and take up the place where it stays. Finally, the melt forms the casting after it is cooled and solidified.
