Patent number: 11229948Abstract: Foamable semifinished product (1) in the form of granules produced from the metal alloy and the foam agent is inserted into the cavity of the closable mould (2) and the liquid (3) with the density that is higher than the apparent (or bulk) density of the resulting foam is led to it. The liquid has a temperature which is higher than the temperature of the melting of the metal alloy; the transfer of the heat to the particles of the foamable semifinished product (1) takes place; it subsequently expands, whereby it is supported by the liquid (3). During the expansion at least part of the liquid (3) is pushed by the expansion itself out of the mould (2) through the opening. The liquid (3) allows the regulation of the pressure of the environment of the foam agent, too, which helps to set exactly the moment of expansion. The metal melt can be advantageously used as liquid (3). The melt can partially remain in the mould (2) so the hybrid structure of the component is created.Type: GrantFiled: December 15, 2015Date of Patent: January 25, 2022Assignee: USTAV MATERIALOV A MECHANIKY STROJOV SAVInventors: Frantisek Simancik, Lubomir Pavlik, Jan Spanielka, Peter Tobolka

Patent number: 10755821Abstract: Composite for the transfer of the heat between the hot and cooled surface, whereby the composite is resistant to high temperatures, includes at least two components, one of the components is produced by longitudinal segments (1) with the melting temperature that is higher than 1300° C. and which are separated from each other by the filling (2) with the higher heat conductivity and thermal expansivity, which is in the direct contact with the cooling medium in the channel (3). Both components are in the direct contact with the hot environment surrounding the composite, whereby the overall surface formed by the segments (1) is 50 to 95% of the overall hot surface of the composite. The longitudinal axis of the segment (1) is primarily oriented in the direction of the shortest line connecting the hot surface with the cooled surface of the composite with the allowed deviation of 45° at maximum, whereby in the direction from the hot to the cooled surface it can cross one boundary between the components at maximum.Type: GrantFiled: December 28, 2015Date of Patent: August 25, 2020Assignee: USTAV MATERIALOV A Mechaniky Strojov SAVInventors: Stefan Kavecky, Pavol Stefanik, Karol Izdinsky, Frantisek Simancik

Patent number: 7754140Abstract: A method for producing dimensionally accurate metal foam from a foamable, powder metallurgically produced metal semifinished product having a melting point >200° C. involving: the introduction of material, which is capable of foaming above 200 ° C., into a mold which has a coefficient of expansion of less than 3 K?1 Controlled heating of the foamable material inside the mold is performed while radiators foam the material, and the foamed product formed thereby removed from the mold. A device for producing dimensionally accurate thermally foamed metal foam parts that is has a thin-walled mold, which is stable at the melting temperature of the metal foam and which has a coefficient of expansion of <3K?1; a controllable irradiating device, and; a controller that controls the irradiating device based on the measurement given by a radiation measuring device.Type: GrantFiled: March 25, 2004Date of Patent: July 13, 2010Assignee: Alulight International GmbHInventors: Walter Rajner, Frantisek Simancik

Publication number: 20020127425Abstract: The invention relates to the production of forms or similar from foamed metal based on aluminum or other metals. Semi-finished product bodies or similar consisting of a foamable semi-finished product material obtained by compacting a mixture of at least one matrix metal powder and at least one expanding agent which releases a foaming gas are placed into a foaming mould or similar where they are geometrically arranged in the desired manner and then heated to a temperature in the range of melting temperature of the matrix metal. Once the mould has been filled, the foaming process is concluded and the resulting foamed metal forms are shaped out.Type: ApplicationFiled: January 25, 2002Publication date: September 12, 2002Applicant: MEPURA METALLPULVERGESELLSCHAFT MBH RANSHOFENInventors: Eric Wolfsgruber, Helmut Worz, Frantisek Simancik

Patent number: 5865237Abstract: A method of making castings of metal foam in which compacts of the metal, e.g. aluminum, and a gas-producing foaming agent are heated in a chamber from which the foaming mass is driven completely into the mold cavity so that some residual foaming can complete the distribution of the foam in the mold cavity. The volume of the compacts is selected such that upon complete foaming, it will fill the mold cavity.Type: GrantFiled: April 18, 1997Date of Patent: February 2, 1999Assignee: Leichtmetallguss-Kokillenbau-Werk Illichmann GmbHInventors: Franz Schorghuber, Frantisek Simancik, Erich Hartl
