What is described is a process for producing an article for use in the foundry industry, selected from the group consisting of molds, cores, feeder elements and molding material mixtures, comprising the following steps: (S1) producing or providing a binder system comprising the following components in three spatially separate vessels: a component (A) comprising particulate amorphous silicon dioxide, a first liquid component (B) comprising waterglass, and a second liquid component (C) comprising aluminate ions dissolved in an aqueous phase, (S2) contacting a mold base material (D) and constituents of all the said components (A), (B) and (C) of the binder system in predetermined ratios in one or more steps, so as to result in a molding material mixture in which the aluminate ions and the particulate amorphous silicon dioxide are mixed wholly or partly into the waterglass, wherein steps (S1) and (S2) are conducted in a facility for producing molding material mixtures. Also described are a corresponding molding material mixture and apparatuses and uses

A mold device of related art has a problem that a total volume of the device becomes large. In an example aspect of the present disclosure, a mold device includes a fixed mold base for supporting a fixed mold, a mobile mold base for supporting a mobile mold, a frame to which the fixed mold base is fixed, provided to extend in a direction in which the mobile mold base is moved, and formed into a wall shape, and holding means for movably supporting the mobile mold base to the frame. The frame is provided along at least one side of the mobile mold base except an upper surface thereof with the mold device installed, and the holding means support the mobile mold base at one side of the mobile mold base.

An assembly includes a first mold component defining a first portion of a mold cavity and a first slot. The first slot corresponds to a first portion of a retention channel. The assembly also includes a second mold component defining a second portion of the mold cavity and a second slot. The second slot corresponds to a second portion of the retention channel. The assembly also includes a connector having a cross-sectional shape corresponding to a cross-sectional shape of the retention channel. The connector has thermal expansion characteristics that are different from thermal expansion characteristics of the first and second mold components such that when the first and second mold components are in contact and the connector is inserted into the retention channel, heating the assembly causes differential thermal expansion of the connector and the mold components resulting in a clamping force between the mold components.

A sand molding apparatus and method, whereby cope and drag portions of a sand mold are formed simultaneously via pressurized sand delivered to each side of a pattern in a perpendicular trajectory. Two opposing sand shooting passageways include a vertical inner side wall and a horizontal inner side wall extending at an angle from the vertical inner side wall. A sand shooting plate at the outlet of each sand shooting passageway includes removable and interchangeable port and cover inserts that can be arranged in custom arrays within the sand shooting plate.
