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: Understand the terminology in metal casting. In metal casting, a mold contains a system of channels to guide the molten metal. This is called the gating system.
Step 2: Identify the function of a pouring funnel. A pouring funnel, also called a pouring cup or basin, is the opening at the top of the gating system. Its primary and direct purpose is to receive the molten metal from the crucible or ladle and guide it smoothly into the main channel (the sprue), minimizing turbulence and splashes. Therefore, its use is to pour the molten metal into the mold system.
