摘要： Thixoextrusion molding apparatuses and methods are provided. One embodiment of the apparatuses comprises: a container having a first through-hole storing 10 to 30 parts by weight of a semi-solid billet therein and a heater installed outside the first through-hole to maintain the temperature of the semi-solid billet constant; a stem insertable into the first through-hole from the front of the container to pressurize the semi-solid billet in the backward direction; a die ring coupled to the back of the container and having a plurality of coolant inflow/outflow holes to prevent thermal deformation in the circumferential direction; a die body disposed inside the die ring and having a second through-hole, which is in communication with the first through-hole of the container and has a smaller diameter than the first through-hole of the container, through which the semi-solid billet is extruded and a plurality of thermocouple insertion holes for measuring the temperature of the semi-solid billet; a die body support coupled to the back of the die body inside the die ring and having a plurality of coolant inflow/outflow holes so as to change the phase of the extruded semi-solid billet to a solid extrudate; a die balance support held in close contact with the die body support and coupled to the back of the die ring; and a cooling unit coupled to the die balance support to cool the solid extrudate. According to the apparatuses and methods, metals can be molded under a low extrusion pressure, the life of the apparatuses is prolonged, the strength of the metal products is improved, the ignition of the metals is inhibited during processing, the amount of a protective gas used is reduced, and the formation of welding lines is inhibited.
