A pouring funnel in a mold, which conveys molten metal to the main body of the sculpture. It then flows through the mold to the form, gates, vents, and risers.
The vertical channel that connects the pouring cup with the runner system. Design consideration must prevent starving the flow of molten metal into the pattern.
The round, tapered material, which connects the loading chamber or nozzle with the runner system or the piece part.
The opening in the mold where the metal is first poured.
The feed opening provided in injection molding between the nozzle and cavity or runner system.
The channel, usually vertical, that the molten metal enters (Fig. 3).
Metal that fills the conical passage (sprue hole) which connects the nozzle with runners.
The initial entry point of rubber into a mold. In a simple mold, it is the same as a gate.
The main opening into a mold cavity through which a plastic material is introduced into the mold.
The main feed guide that runs from the outer face of an injection or transfer mold gate into a single cavity mold or to runners in a multiple cavity mold.
Vertical mechanism connected to the pouring cup that transfers the molten metal to the runners.
an opening through which molten metal is poured into a mold
In injection molding, the passage that brings molten plastic from the end of the extruder-to the passage or passages that will distribute the plastic to the mold cavities. In a single cavity mold, the sprue would lead directly to the gate. In a multicavity mold, the sprue would join the runner system.
The feed channel and opening in the direction of flow in an injection or transfer mold.
either a channel through which metal or plastic is poured into a mould or the metal or plastic which has solidified in a sprue; often holds pieces in model kits
Wax or metal used to form the aperture or passageway for molten metal to flow into a mold to make a casting; also the metal which later fills the sprue hole.
a primary channel for rubber to flow through in filling a mold; the leftover cured rubber from the channel is also called the sprue
The opening, or hole, through which the casting medium is poured into some molds; also refers to the waste material which hardens in the opening and often adheres to the cast. Alternately, the term can also apply to the piece of material which the mold maker originally places on the specimen to form the opening in the mold. Synonymous with vent, pour hole.
The primary feed channel that runs from the outer face of an injection mold to the runner or the gate.
The channel through which liquid casting material is poured during the casting process. After the cast has hardened, some material (typically resin) will remain in this channel, and must be removed before the model is built. Injection molded models will come attached to a rectangular sprue, or "part tree," as it is sometimes called.
The initial inlet into the die set for injection molding feedstock. The sprue is usually filled by the nozzle and is tapered for easy extraction after mold filling. It feeds the runner system, which in turn feeds the gate.
The main channel or feed that runs from the pouring cup to the gate system in order to channel the molten bronze into the investment mold.
(downsprue-downgate) The channel, usually vertical, that the molten metal enters.
the part through which plastic flows from the nozzle into the mould during the injection moulding process. The word also means the small, hard piece which remains, which is then broken off leaving a characteristic round scar.
A vertical passageway that takes the molten metal from the pouring basin to the runner. See Runners.
(1) The channel, usually vertical, which the molten metal enters: so-called because it conducts metal down into the mold. (2) The vertical channel connecting the pouring basin with the runner system and terminates in the sprue well at the bottom. See Runners.
n. The manufacturing material that is still attached to game bits when they are taken from the packaging for the first time. Usually refers to injection-molded plastic, but sometimes is used to refer to the excess cardboard from which game materials must be punched.
The route the resin takes from the point where it enters the mold until it reaches the runner(s). When solidified, it remains attached to the part via one or more runners and is typically removed in finishing.
Feed opening provided in the injection or transfer mould; also the slug formed at this hole. Spur is a shop term for the sprue slug.
In foundry work, a Sprue is the passage through which metal is poured into a mold. The term can also refer to the excess metal on a rough casting, which solidified in the sprue hole. The term has the identical usage in the plastic injection-molding industry.
In casting, a sprue is the passage through which a molten material is introduced into a mold, and the term also refers to the excess material which solidifies in the sprue passage. In sand casting, the sprue is formed by a dowel which is removed from the sand to make the hole into which the metal is poured.
