Vacuume casting mold ventilation process, the molten metal into the mold to rely on air pressure, and then clear the air, forming a vacuume.Vacuume casting is a physical modeling method, it will vacuum technology combined with sand casting, by plastic film to seal the cavity of the sand mold surface and the back, with negative pressure vacuum pump, resulting in a sand mold and outsidepressure sand mold fastening molding, placed sand heart, clamping, casting, waiting for solidification, the lifting of the negative pressure or stop pumping sand mold would become collapsing casting??Vacuume casting has the following advantages??
(1) a moderate degree of vacuum with high compaction of the mold cavity, the casting quality is high.
(2) vacuume casting mold flow analysis with computer simulation, we can predict the generation of casting defects, modeling program designed to dramatically save time, improve production efficiency.
