Question

In the context of Metal Casting process which of the following statement(s) is/are TRUE?

• A. Metal is heated to red hot state and cut into desired blocks and forms.
• B. Molten liquid is poured into moulds.
• C. Runners and risers are used.
• D. Patterns and Cores are used.

Hint:

In metal casting, molten metal is poured into molds, and runners, risers, patterns, and cores are used to ensure proper shape and structure.

Answer 1

The Correct Option is B, C, D

Step 1: Understanding Metal Casting.
In the metal casting process, molten metal is poured into molds to create shapes. Other elements such as runners, risers, and cores are also used to guide the flow of molten metal and create internal cavities.

Step 2: Explanation of terms.
- (A) Metal is heated to a red-hot state for casting, but it is not typically cut into blocks and forms. This is not true in the context of the casting process.
- (B) Molten liquid (metal) is indeed poured into molds, making this statement TRUE.
- (C) Runners and risers are essential in directing the flow of the molten metal and allowing for proper filling of the mold, making this TRUE.
- (D) Patterns and cores are used in the casting process to shape the mold and create internal cavities, making this TRUE.

Step 3: Conclusion.
The correct statements are (B), (C), and (D).
