<p>A facility for vacuum casting and forming mechanises casting procedures in sealingly installed impermeable mould frames on a working surface of a facility for vacuum casting and forming. The full forming procedure is carried out in a pressurised and evacuated mould condition in a covered mould. The cast-in procedure is performed into a covered mould in the evacuated mould condition. The process of hardening in a covered mould takes place at stationary or dynamic vacuum. The procedure of directed cooling takes place in a partially or totally uncovered mould and at stationary or dynamic pressure or vacuum.</p> |
