Any channel that feeds metal to the mold, in contrast to a vent, which lets air escape. Both sprues and vents make up the “sprue system,” which circulates from the pouring cup through the and allows air and casting vapors such as steam to be released. In , “sprue” is the term used for the solid wax rods (rarely reeds or terra-cotta pipes) used to create the channels in the mold. Sprues are also the solid metal that has filled the channels upon cooling, which is generally removed during .

Note: The terms “sprue,” “sprueing,” “sprueing system,” or “sprue system” are most commonly associated with lost-wax casting. For the equivalent would be “gating” or “gating system,” which is where all the other terms (“runners,” “risers,” “gates,” etc.) come into play. In sand and casting the channels are cut directly into the refractory mold. See GI§2.7. Depending on the complexity of the , the sprue or gating systems may also contain other elements with special functions (e.g., reservoirs, chills, drains, traps, jets, etc.).

Translations

French: jet de coulée

Conduit dans le pour le remplissage du moule par le métal liquide. Désigne aussi les mêmes éléments remplis de métal dont il faut débarrasser le bronze après la . Désigne, pour les , les éléments en cire servant à cette fonction.

Note: Dans la zone d’arrivée du métal dans le moule réfractaire est aménagé un « cône de coulée » pour faciliter la , et qui sert également de « masselote ». Les conduits servant pour l’évacuation des gaz portent un nom spécifique, évents (, 335; , 39–42; , 70–75; , 2:264; , 5; , 627; ; , 254, 373; , 66; , 269; ; ). Pour l’évacuation de la cire on parle de tire–cire (, 763). Certains auteurs emploient le terme d’artifices de fonderie (, 59; , 27). Pour certains d’entre eux (), les artifices de fonderie désignent également, dans le cas de moules à pièces, les éléments servant au positionnement des moules (artifices de centrage).
