Zusammenfassung:The mold formed of resin-bonded sand includes a vertical sprue in fluid flow communication with a horizontal chamber reservoir underlying the mold cavity defining the thin wall structure. The thin wall cavity portion is positioned about a common horizontal level above the reservoir. Vertical runners feed the metal from the horizontal reservoir up into the cavity. The number and location of these runners are such as to fill the cavity from several points of entry with uniform temperature metal before any solidification occurs.
