摘要： The present invention provides a pressure casting method of a magnesium alloy. In the method, a molten magnesium alloy is cooled to form a partially molten state containing a solid-phase, and the partially molten state is further cooled to form a solid-phase granularly crystallized solid material. The solid material is partially-melted and pressure cast into a mold by a molding machine. A ratio of primary crystals in said solid material is set to 55 to 65%. The solid material is partially-melted in a solid-phase and liquid-phase coexisting state at a selected heating temperature so that a semi-solid having thixotropic properties and having the size of a main solid phase of 50 to 250 μm and a solid-phase ratio of 30 to 70% is formed. The semi-solid is pressure cast into a mold through a nozzle while maintaining the semi-solid state to form metal products having a ratio of primary crystals of 20 to 50%.

摘要： A low melting point metal material is made to a thixotropic state in which liquid phases and solid phases coexists. In the thixotropic state of the low melting point metal material, a carbon nano material is kneaded with the low melting point metal material and forms a composite material. Thus obtained composite material is supplied to a metal molding machine and injected into a mold in a thixotropic state or a completely molten state of the metal so that the composite material fills the mold, thereby the composite material is molded to a composite metal product. With the above process, it is possible to injection mold the composite metal product to which the characteristics of the carbon nano material are applied.

摘要： An injection molding process wherein the times of heating to melt a resin are reduced to minimize the thermal hysteresis and to decrease the deterioration of physical properties caused by the thermal hysteresis, so that high quality information recording disks may be produced. A molding process wherein the plasticating and the injection and filling of a material resin are carried out in separate cylinders, allows constant molding for a long period of time. A material resin such as polycarbonate is supplied without predrying to an injection apparatus for a first time molding. Resin is kneaded by the apparatus while volatile components are heated to be vaporized and exhausted through a vent port. An inert gas atmosphere is provided within the cylinder to prevent the material resin from being oxidized. Since predrying can be dispensed with, the thermal hysteresis will be extremely small and the deterioration of the resin caused by such heating may be suppressed. Also, there is less chance of generation of carbonized black spots caused by foreign matter, molding failures caused by hydrolysis may be eliminated, and residual monomers can be vaporized and exhausted concomitantly.
摘要翻译： 降低加热熔融树脂的时间的注射成型工艺被减少以最小化热滞后并减少由热滞后引起的物理性能的劣化，从而可以产生高质量的信息记录盘。 一种成型方法，其中塑料和树脂的注入和填充在单独的圆柱体中进行，允许长时间恒定的模制。 提供诸如聚碳酸酯的材料树脂，而无需预先注入到注射装置中以进行第一次成型。 通过该装置将树脂捏合，同时将挥发性组分加热以通过排气口蒸发并排出。 在气缸内设置惰性气体环境，以防止材料树脂被氧化。 由于可以省去预干燥，所以热滞后将非常小，并且可以抑制由这种加热引起的树脂的劣化。 此外，由异物引起的碳化黑斑的产生机会较少，可能消除由水解引起的成型失败，并且残留的单体可以同时蒸发和排出。
