A manufacturing method of a thermoelectric module comprises forming a first wax model in which the first thermoelectric elements are arranged in a predetermined pattern, forming a first mold from the first wax model, casting a group of the first thermoelectric elements by pouring molten metal of a first thermoelectric material into the first mold to solidify the molten metal, forming a second wax model that represents arrangement of second thermoelectric elements to form the thermoelectric module by being connected with the first thermoelectric elements, forming a second mold from the second wax model, casting the group of the second thermoelectric elements by pouring molten metal of a second thermoelectric material into the second mold to solidify the molten metal, and connecting the group of the first thermoelectric elements with the group of the second thermoelectric elements electrically in series.

A powder-containing oil-based lubricant for die contains 60 to 99% by mass of an oil-based lubricant consisting of oil, 0.3 to 30% by mass of a solubilizing agent, 0.3 to 15% by mass of an inorganic powder and 7.5% by mass or less of water, the lubricant being electrostatically applied to a die. The powder-containing oil-based lubricant may be applied to a die by electrostatic spraying. The electrostatic spray apparatus includes a device that imparts static electricity to the powder-containing oil-based lubricant and an electrostatic spray gun installed on a multi-axis robot.

An apparatus and process for manufacturing a disc rotor made of a metal-based composite material, which enables stabilization of a preform support within a disc rotor casting cavity while minimizing likelihood of damaging of preforms. The apparatus comprises a lower dieand a movable core assemblywhich constitutes a disc rotor casting cavity; a preform supporting portionwhich is provided on a movable core assembly; a pressurizing and shaping portionof an upper diefor applying pressure upon a molten metal accommodated in the cavity; and a preform biasing mechanismhaving a biasing facewhich can be brought into a face-to-face contact with the upper face of a preformwhich is supported on the preform supporting portion. On application of pressure upon the molten metal, the preform biasing mechanismbiases the preformvia the biasing faceto prevent the preformfrom being shifted due to an increase in the pressure upon the molten metal.

A disk rotor is produced using pre-forms. A manufacturing deviceincludes lower moldand upper mold. The lower moldincludes support block, main body part of the lower mold, inclined pins, core elementsand slider. In securing and supporting pre-formsA,A, a cylinderis actuated to cause upward movement of the support blockand the main body part of the lower mold, during which movement, core elementsand sliderare slid relatively outwards along inclined pins. In this state, the pre-formsA,A are guided to preset sites. The support blockand the main body part of the lower moldare then moved downwards, during which movement, core elementsand sliderare slid relatively inwards along the inclined pins. In this state, the pre-formsA,A are supported and secured stably to define a cavity.

A casting device for metallic product includes a main unithaving a pressurizing chamberand casting cavitiesfor accommodating a metallic material M, a pressurizing unitfor pressurizing the metallic material M contained in the pressurizing chamberto cause the metallic material to flow into the casting cavitiesand a blade unitprovided between the pressurizing chamberand the casting cavities. The blade unitincludes a scraper edgefor scraping the outer layer of the metallic material M pressurized by the pressurizing unit. After the end of the scraping operation for the outer layer Mof the metallic material M, the blade unitis moved by the first driving unitfrom the scraping position Ato a disengaging position. Thereby, the metallic material can be readily separated from the blade unit.
