Difficulty: Easy
Correct Answer: All of the above
Explanation:
Introduction / Context:
Industrial plastic forming relies on several foundational processes. This question validates whether you can identify which statements correctly map processes to products and methods.
Given Data / Assumptions:
Concept / Approach:
Each listed process has a canonical application: blow moulding for hollow articles like bottles; calendering for continuous sheets/films; laminating for resin-bonded composites (paper or fabric); and moulding as the general method of shaping in a cavity.
Step-by-Step Solution:
Verification / Alternative check:
Basic manufacturing texts and polymer processing guides match these definitions and typical applications.
Why Other Options Are Wrong:
Individual process statements are correct but incomplete; the aggregate correctness is captured by “All of the above.”
Common Pitfalls:
Confusing calendering with extrusion casting; forgetting that blow moulding specifically targets hollow shapes.
Final Answer:
All of the above
