Abstract: Provided is a rheoforming apparatus that ensures the manufacture of products with fine, uniform, spherical particles, with improvements in energy efficiency and mechanical properties of the products, cost reduction, convenience of forming, and shorter process duration. The apparatus includes a first sleeve, an end of which is formed with a slurry outlet port for releasing a slurry, a second sleeve for retaining a molten metal, an end of which communicates with the first sleeve, a sealing member for opening or closing the end of the second sleeve, a stirring unit for applying an electromagnetic field to the second sleeve, and a plunger, which is slidably inserted into the other end of the second sleeve to press the slurry manufactured in the second sleeve.

Abstract: Provided is an apparatus for manufacturing a high-quality semi-solid metallic slurry containing fine, uniform spherical particles that can be readily and conveniently applied to a subsequent process, with improvements in energy efficiency and mechanical properties, cost reduction, convenience of casting, shorter manufacturing time, and easy discharge. The apparatus includes: at least one sleeve with two open ends, through one of which molten metal in liquid state is loaded into the sleeve; a stirring unit which applies an electromagnetic field to the molten metal in the sleeve; and a shutter unit which closes the other end of the sleeve to form a base of the sleeve and opens the base of the sleeve to discharge a slurry after manufacture from the sleeve.
