The present invention relates to a filtration method, a filter-incorporated tip and a filtration device, and its object is to perform efficient and swift isolation of a target substance. The filtration method therefore comprises: a liquid introducing step to introduce a liquid into a filter-incorporated tip through a guide opening portion thereof, wherein the filter-incorporated tip has a nozzle-tipped container and a filter, the nozzle-tipped container has a guide opening portion that can be directly or indirectly fitted to an air nozzle capable of ejecting a gas and a front nozzle portion capable of delivering the liquid by the ejection of the gas from the air nozzle, and the filter is locked in the nozzle-tipped container to partition the interior of the nozzle-tipped container into the guide opening portion side and the front nozzle portion side and is adapted to temporarily hold the liquid and isolate a predetermined substance as the liquid passes through the filter, with the nozzle-tipped container coupled to the air nozzle on the guide opening portion side; a coupling step to directly or indirectly couple the filter-incorporated tip containing the liquid to the air nozzle; and a pressure application step to eject the gas from the air nozzle into the coupled filter-incorporated tip.

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.

The present invention provides an aluminum alloy for die castings that has superior castability and corrosion resistance. The amounts of Mn, Fe and Cu contained in the aluminum alloy components for die castings were determined to have a considerable effect on the corrosion resistance of the aluminum alloy. Therefore, the aluminum alloy for die castings of the present invention contains 9.0 to 12.0% by weight of Si, 0.20 to 0.80% by weight of Mg, and 0.7 to 1.1% by weight of Mn+Fe, the Mn/Fe ratio is 1.5 or more, the amount of Cu as impurity is controlled to 0.5% by weight or less, and the remainder is composed of aluminum and unavoidable impurities.

A casting method and casting mold able produce a casting having an island and connecting portion is disclosed. A casting having a body, an opening provided so as to pass through the body, an island arranged separated from the body in the opening, and a connecting portion joining the island and body is cast using a casting mold. The casting mold is provided with a body gate connected to a body cavity for forming the body and an opening gate connected to an island/connecting portion cavity for forming the island and the connecting portion. The body gate and opening gate are connected to a runner through body pin gates and opening pin gates; in addition, a die casting mold able to suitably change between a three-part mold structure and a two-part mold structure to cast a die casting is disclosed. The three-part mold structure die casting mold, a movable mold, a first cavity, a connection sleeve, a first runner, a pin gate, and an extension sleeve. When forming the two-part mold structure die casting mold, the fixed mold is removed, the extension sleeve insert inserted in the extension sleeve is removed, and the pin gate is filled by a pin gate insert. Further, the intermediate mold insert and the movable mold insert are replaced to form the two-part mold structure die casting mold forming the second cavity and second runner moving the movable mold with respect to the intermediate mold.
