摘要： PROBLEM TO BE SOLVED: To solve a problem of remaining material at completing time of work and at provisional stopping time of the work by discharging the remaining material in a fully molten state, in the case of using a low melting point metal alloy showing a thixotropy characteristic in the solid-liquid coexisting zone as a forming material and melting the alloy into a semi-solid and injection-forming it.
SOLUTION: A method for forming the low melting point metal alloy comprises: heating the remaining semi-solid material at the completing time of formation to the temperature to not lower than the liquidus temperature and melting; injecting the material in a fully molten state and discharging it from a heating-holding cylinder; and stopping the heating and completing the forming work. The discharge of the remaining semi-solid material is performed by supplying a metal raw material having the same composition as the forming material. The provisional stopping of the formation is performed in a state in which accumulated semi-solid is formed in a fully molten state by raising the temperature of the heating-holding cylinder to not lower than the liquidus temperature. While performing the discharge by injecting the fully molten material and the supplying of the forming material at the restarting time of formation, the temperature of the heating-holding cylinder is dropped to the temperature in the original solid-liquid coexisting temperature zone, and the formation is started after replacing the inner part of the heating-holding cylinder with the supplied forming material.

摘要： PROBLEM TO BE SOLVED: To solve such problem during temporal stop, when injection-forming the metallic blank as a forming blank showing thixotropy characteristic in a solid-liquid coexisting temperature range while melting a semi-solid, by keeping the semi-solid in the perfect-melting state.
SOLUTION: The temporal stop of the formation is performed so that the stored semi-solid material becomes the perfect melting state by rising the temperature of a heating holding cylinder to the temperature of a liquidus temperature or higher. This temperature is kept until the start of the formation. While performing the discharge with the injection of material in the perfect melting state and the supplying of forming material when reopening the formation, the temperature of the heating holding cylinder is lowered to the temperature of the original solid-liquid coexisting temperature range. The formation is started after replacing into a forming material supplied in the heating holding cylinder.

摘要： PROBLEM TO BE SOLVED: To improve the ease of insertion and heating efficiency of a cylindrical metallic material by setting the clearance with a melting cylinder that a heating/retaining cylinder of a metal forming machine has, from the linear expansion coefficient of the metallic material and the linear expansion coefficient of the melting cylinder when thermally expanded.
SOLUTION: The cylindrical metallic material inserted into a melting cylinder is melted halfway or completely by a heating means on the outer peripheral surface of the melting cylinder. The clearance between the inner peripheral surface of the melting cylinder and the outer peripheral surface of the cylindrical metallic material is set from the linear expansion coefficient of the metallic material and the linear expansion coefficient of the cylindrical metallic material. The setting, as defined by the inner diameter of the melting cylinder and the diameter of the cylindrical metallic material when thermally expanded, is limited to within a range that does not exceed 1.0 mm but permits the insertion of the non-thermally-expanded metallic material into the thermally-expanded melting cylinder at the temperature of the heating means.
