[0002] Lost foam casting (also known as full mold casting) is a new casting method that combines paraffin or foam models with similar size and shape to the casting into a model cluster, brushes refractory coating and dries it, buries it in dry quartz sand for vibration molding, pours it under negative pressure, vaporizes the model, and the liquid metal occupies the position of the model. After solidification and cooling, it forms a casting. Among them, the sand box for lost foam casting plays a very important role in the lost foam casting process.
