Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Impact extrusion is a high-speed cold forming process where a punch strikes a metal blank and forces material to flow backward or forward.
It is widely used for producing hollow cylindrical components.
Step 1: Understand process nature.
A punch impacts a slug and forces metal to flow plastically.
Step 2: Material flow.
• backward flow → hollow cup formation
• forward flow → small extruded section
Step 3: Typical products.
• toothpaste tubes
• aerosol cans
• small hollow shells Final Answer: \[ \boxed{\text{Short lengths of hollow shapes}} \]
