Patent concerning lost-wax casting for aero engine components:
"La carapace est conçue de sorte que l’introduction du métal dans les éléments aubagés de carapace s’effectue uniquement via les bras de coulée, présentant chacun une seconde extrémité raccordée sur l’un des éléments aubagés de carapace."
"L’assemblage de ces modèles sur des bras de coulée également en cire, eux-mêmes raccordés à un distributeur de métal en cire, permet de constituer une grappe qui est ensuite plongée dans différentes substances afin de former autour de celle-ci une carapace de céramique d’épaisseur sensiblement uniforme."
"Plus précisément, la carapace est réalisée de manière à ce que des bras de coulées supplémentaires soient agencés autour du distributeur de métal sur lequel ils sont raccordés par une première extrémité."
"Le distributeur de métal alimente non seulement les bras de coulée différents, mais également un descendant de coulée central, dont l’extrémité est reliée à des bras de coulées inférieurs agencés autour de ce dernier."
Exhausting all the habitual technical translation sources, I googled the phrase "casting arm" but came up only with a couple of rare instances which were different to what is meant here, where the molten metal clearly flows *through* the bras de coulée.

Investment casting, though a thousands of years old technology, is still a vital process in modern day manufacturing particularly in China. We can see from the above description with the use of the tree patterns, it is primarily used for the manufacturing of smaller parts (which are arranged as the “branches” of the tree).
http://thelibraryofmanufacturing.com/investment_casting.html
Since the mold does not need to be opened castings of very complex geometry can be manufactured. Several wax patterns may be combined for a single casting. Or as often the case, many wax patterns may be connected and poured together producing many castings in a single process. This is done by attaching the wax patterns to a wax bar, the bar serves as a central sprue. A ceramic pouring cup is attached to the end of the bar. This arrangement is called a tree, denoting the similarity of casting patterns on the central runner beam to branches on a tree.

Yes, distributeur de metal: sprue but gate is better

Note from asker:
| thanks very much... you gave me some clues which led me to look up "sprue" in Wikipedia: "A sprue is the passage through which liquid material is introduced into a mold". What do you think? |
| or possibly "gate": http://castinghobbyfaq.bareboogerhost.com/sgr.shtml |

Comment: "thanks... I went for gate in the end"
Something went wrong...
