Abstract

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.

Claims (7)

1. 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 comprising:

substantially equilibrating flow of the metallic-molding material through a collection of branches from a molding system into the mold by:

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;

conveying the metallic-molding material from the input through the collection of branches of the conduit assembly over to the outputs;

forming plugs in the outputs;

chronologically blowing out the plugs from the outputs into the mold cavity of the mold; and

removing an amount of heat energy from a branch of the collection of branches at a location away from an output of the branch, and in response the metallic-molding material becomes solidified to form a patch of solidified molding material attaching to the branch, and the patch of solidified molding material reducing flow of the metallic-molding material through the branch and into the mold prior to the mold becoming filled with the metallic-molding material, so that an amount of flow of the metallic-molding material through another branch of the collection of branches will be greater than the amount of flow of the metallic-molding material through the branch.
