The sprue is the primary channel in a precision casting gating system that delivers molten metal from the pouring cup to the mold cavity.
In precision casting, particularly investment casting and die casting, the sprue is a critical component of the gating system. It serves as the main vertical conduit through which molten metal flows from the pouring basin or cup into the runner system and subsequently into the mold cavities. The sprue's design directly influences metal flow velocity, turbulence, and temperature distribution, impacting casting quality, defect formation, and yield. It is typically tapered to prevent air aspiration and ensure smooth, controlled filling.

Tapering prevents air aspiration into the molten metal stream, reduces turbulence, and maintains adequate flow velocity to avoid premature solidification, ensuring complete mold filling.
Poor sprue design can cause defects like porosity, cold shuts, or inclusions due to turbulent flow, improper thermal gradients, or gas entrapment, directly impacting mechanical properties and yield.
