4.3. Manufacturing Methods

Try these first

1. 1.

   What is addition polymerization?

   Hint

   Think about how you build something without leftovers.

2. 2.

   Name a common product created through blow molding.

   Hint

   Think of what you drink from.

3. 3.

   What is the primary outcome of addition polymerization?

   • By-products are produced
   • Monomers join cleanly
   • Only heat is generated

   Hint

   Consider which process leaves nothing behind.

4. 4.

   True or False: Compression molding is primarily used for thermoplastics.

   • True
   • False

   Hint

   Think about what happens to the plastic after it's molded.

5. 5.

   Design a new product using extrusion molding. Describe your product and justify why extrusion is the best method.

   Hint

   Consider the need for uniformity in products.

6. 6.

   Evaluate the impact of choosing wrong molding techniques on the performance and application of plastic materials in civil engineering.

   Hint

   Think about how mismatches could lead to failures in structures.
