Abstract
A device for molding objects includes a mold having a molding space enclosed therein and adapted to be filled by a fluid mold material intended to solidify therein. The fluid mold material is injected under pressure into the molding space and solidifies under this high pressure. A chamber receives the mold and is filled with a medium. The medium filling the chamber and surrounding the mold is pressurized. The pressurized medium acts upon the mold from all directions with at least the same pressure magnitude as the pressure of the mold material within the mold. Therefore, the mold is isostatically balanced by the forces acting upon the mold by the mold material and the medium.
