    摘要: A molten metal vessel includes a first chamber for containing molten metal such as molten aluminum therein, a filtration chamber in which impurities contained in the molten metal are removed, and a second chamber for reserving clean molten metal to be supplied to a casting die. The molten metal flows from the first chamber to the second chamber through the filtration chamber. A pair of filters, preferably a pair of cylindrical filters, are disposed in the filtration chamber, so that the impurities contained in the molten metal can be filtered twice. The filters are attached to the bottom of the filtration chamber where molten metal oxides hardly develop, so that the filters are easily replaced with new ones for the maintenance purpose. A rod-shaped heater may be disposed in the cylindrical filters to keep the molten metal temperature in a strictly controlled range. Thus, the impurities are effectively removed from the molten metal through the filters which are easily replaceable.

    摘要: The newly proposed cast aluminum alloy product has the composition consisting of 6.5-8.0% Si, 0.25-0.45% Mg, 0.08-0.40% Fe, 0.001-0.01% Ca, P less than 0.001%, 0.02-0.1% Ti, 0.001-0.01% B, optionally one or two of 0.05-0.3% Cr and 0.05-0.2% Mn, and the balance being Al except inevitable impurities. It has the metallurgical structure that an α-Al phase in a surface layer is of average grain size different by 50 μm or less from an α-Al phase in an inner part, and that a maximum size of eutectic Si particles is 400 μm or smaller. It is manufactured by injecting a molten aluminum alloy into metal dies at an injection speed of 0.05-0.25 m/second, and then cooling the injected alloy at a cooling speed of 20° C./or higher in a temperature range between liquidus and solidus curves in a state charged with a pressure of 30 MPa or higher. Since the cast product is good of ductility, it is used as a member for coupling another member therewith by calking or the like.

    摘要: A die-casting method that eliminates the need to inject insulation. By injecting molten metal sufficiently quickly after injecting tip lubricant, die-cast products may be removed from the mold even without injecting isulation. To this end, a movable die may at least begin moving toward a fixed die before tip lubricant is injected. The tip lubricant may be injected from a molten metal pouring port in a shot sleeve or from the movable die toward the shot sleeve. Tip lubricant which has been introduced into the shot sleeve is conveyed into the die cavity by movement of the molten metal, thus coating the die cavity inner surface.
