US Patent 7387152 Metallic-molding-material runner having equilibrated flow

Disclosed a method of a metallic-molding-material runner system for filling a metallic-molding material into a mold cavity of a mold, the metallic-molding material includes a metallic component, the method including: substantially equilibrating flow of the metallic-molding material through a collection of branches from a molding system into the mold by; (i) receiving the metallic-molding material from the molding system through an input being defined by a conduit assembly, the conduit assembly including the collection of branches each being configured to pass the metallic-molding material from the input over to outputs of the collection of branches; (ii) conveying the metallic-molding material from the input through the collection of branches of the conduit assembly over to the outputs; (iii) forming plugs in the outputs; and (iv) chronological blowing out the plugs from the outputs into the mold cavity of the mold.
