Question

What is the use of 'pouring funnel' in metal casting?

• A. To escape the gas or air
• B. To pour the molten metal
• C. To blow the investment
• D. To hold the mold

Hint:

The parts of a casting mold system have specific names: the Pouring Funnel (or cup) is for entry, the Sprue is the vertical channel, Runners are horizontal channels, and Gates are the entry points into the mold cavity. Vents are used to let gas escape.

Answer 1

The Correct Option is B

Step 1: Metal casting terminology. The gating system directs molten metal flow within a mold.
Step 2: Pouring funnel function. The pouring funnel (pouring cup/basin) sits atop the gating system. It receives molten metal, guiding it from the crucible/ladle into the sprue (main channel) to reduce turbulence and splashing. Its function is to introduce the molten metal into the mold.
