Patent number: 8083099Abstract: A method for producing a multicomponent compound involves pressing components out of cartridges by means of pistons. The method has particular applicability in connection with dental applications. The method prevents pressing the components initially under high pressures. At the beginning of the pressing-out process, a pressure lower than the characteristic pressing-out pressure of the components from the cartridges is employed. Feed speeds are adjusted to constant value as a function of the pressing-out behavior of the components which are compared with stored or calculated values for a known material.Type: GrantFiled: June 14, 2006Date of Patent: December 27, 2011Assignee: Ernst Muhlbauer GmbH & Co.
