Vacuum Casting is a physical forming process, its fundamental principal is: fill in the sand box with air exhausting pump by dry and fine sand, vibrated slightly and compacted, followed by covering the molded surface and sand box with plastic film, then vacuumed the sand box. The casting would be sized by the pressure difference between inside and outside the sand box, then withdraw the mold and seal the sand box, casting made under the vacuum situation.

The application of oxygen blowing technology at the bottom of the furnace greatly improves the purity of the melt.

Cleaness.

Bottom Oxygen Blowing process is to input oxygen into the furnace slowly through the inlet holes located on the furnace shell and run through the furnace shell and lining, while the temperature inside the furnace is increasing. By this way, the flowing speed of molten material inside the furnace got increased, and the mixing evened.
