Question

In extrusion, the primary function of the transition zone is to:
A. compress the polymer
B. melt the polymer
C. support the screen pack
D. contribute for he back pressure

• A. A and B only
• B. A and C only
• C. B and D only
• D. A and D only

Hint:

The transition zone is critical for proper polymer melting and compression in extrusion processes.

Answer 1

The Correct Option is A

The transition zone in extrusion is responsible for compressing and melting the polymer, ensuring smooth flow toward the die for further shaping.
