  • Method and device for mixing under vacuum mixtures used in dental, goldsmith fields or the like
    Patent number: 4577973
    Abstract: A mixture of a powder and a liquid is formed and poured, under vacuum into suitable containers for the subsequent production of molds to be employed in dental and goldsmith fields. In order to achieve the best degassing conditions and to avoid the production of foams and bubbles in the course of the vacuum mixing step, separate degassing of the liquid and powder components of the mixture is performed in separate vessels before the mixing step, followed by a combination, for example by pouring, of the components in one of the vessels, while maintaining the vacuum conditions.
