Then put on sand box and make sand into vacuum situation, which can make the internal and external pressures different to make the dry sand compact so that it can form the needed sand molds.
Vacuum molding casting's surface is in good quality, less casting defects, easy mold release, and high precision in cast size, and the sand is without binder, thus, it is almost full recovery, which reduces material costs, and it is gradually wide used.
