Lost foam casting process is a very popular energy-saving and environmentally friendly casting process, but because of the different shapes of a series of castings such as machinery and equipment, how to control different types of lost foam casting? First, the dry sand modeling of the vanishing mold is the first step to add dry sand to the sand box. In order to ensure that the dry sand is filled in place, first add a certain thickness of bottom sand to the sand box and shake it tightly, then put it into the model cluster. Then, add a certain thickness of dry sand, bury the model cluster to one-third to one-half, and then perform appropriate vibration to promote the filling of the dry sand into the cavity of the model. Finally, the sand box is filled for vibration, and the vibration time should not be too long to ensure that the model does not appear to be damaged and deformed, and at the same time to ensure that the paint layer of the lost foam does not fall off and crac...
