摘要： PURPOSE:To make it possible to prepare mixture with stable quality without fear such as dust explosion and the like due to fine dust-size particle by a method wherein granular mixture is produced by granulating slurry-like mixture into granules after being subjected to liquid extraction. CONSTITUTION:Slurry-like mixture, which is produced by mixing wiskers and matrix metal powder with organic solvent, is liquid extracted. After that, by adding with binder and kneading said mixture is granulated into granules having the diameter of about 0.5-1 mm so as to obtain granular mixture 2 by drying in order to feed to an injection molder 20 under vacuum atmosphere. The matrix metal is heated up to a temperature, at which both the solid phase and liquid phase of the metal are present each other, or higher in the gap between an injection cylinder barrel 11 and a screw rotor 12 of the molder. At the same time, the matrix metal is injection-molded from the injection nozzle of the molder into a mold so as to obtain a molded item with required shape. Further, in order to dry the granular mixture 2, the mixture is dried by being heated up to a temperature near the melting point of the matrix metal. Furthermore, after being injected in the mold, the matrix metal is compressed with the mold in order to obtain the molded item.

摘要： PURPOSE:To solidify and mold a powder material with high efficiency and to improve the quality of a molding by putting the powder material into a container, then heating the container successively while the container is exposed to a vacuum atmosphere and subjecting the material to pressurized molding as it is. CONSTITUTION:The powder material 1 to be treated such as metal powder or ceramic powder is supplied from a vessel 2 provided with a discharge pump 18 into a vacuum vessel 16. The powder material 1 flowing down from an outlet 3 of the vessel 2 is conveyed by a moving belt 4 moving at a prescribed speed in the vessel 16 and is heated an route by a heater 5. The heated material 1' is loaded into containers 9, 10 which are kept at a prescribed temp. by heaters 8, 11 and are changeable in position by means of a guide 7. The material 1' is thereafter compacted by a stem 12 of a press mechanism 15, by which said material is solidified and molded.

摘要： PURPOSE:To produce crack less bar-shaped composite material with good productivity by supplying a raw material composed of whisker and metallic powder into a container equipment for extrusion, pressurizing, compacting, heating and extruding it through a die. CONSTITUTION:A die 4 is sealed by a ram 11 and mixed powder material 17 composed of light metal such as Al alloy and whisker such as SiC is supplied by the advance and retreat of a pressurizing stem 15 into a chamber 2 of a container equipment 1. In the chamber 2, the material 17 is compacted by the pressurizing stem 15 at 1,000-3,000kgf/cm in the shape of a billet and heated by a heater 3 uniformly at 500-600 deg.C. Then, the ram 11 of a sealing cylinder equipment 6 is pulled out of the die 4, a die holding plate 14 is engaged with a die back-up body 12 and a pushing force is added to the pressurizing stem 15 to extrude bar-shaped composite material 17B from a billet-shaped material 17A.

摘要： PURPOSE:To produce a good-quality long-sized billet molding without generating joint surfaces by loading and packing a powder material into container molds and compressing the material by a moving mold from the direction orthogonal with the longitudinal direction of the billet, thereby solidifying and molding the material. CONSTITUTION:The powder material 4' which is a powder or granular metal, ceramics or the mixture composed thereof is housed into a metallic mold for molding constituted of the container molds 2, 3. The moving mold 1 is then used and is pushed down to a position 1' from the direction orthogonal with the longitudinal direction of the billet to exert pressure to the powder 4' and to compress, solidify and mold the powder, by which the long-sized billet 4 of L/D>1 (L is the length of the billet, D is the representative length of the billet section) is molded. The solidification and molding in a reduced pressure or vacuum atmosphere is more effective at this time; the molding at the temp. below the solid phase point of Al or Al alloy is advantageous particularly in the case of using the powder prepd. by mixing SiC whiskers and Al or A$; alloy powder as a raw material. The long-sized billet is thereby molded without requiring joining in the molding stage.
