4.4. Rolling and Extrusion

Try these first

1. 1.

   What is rolling in metalworking?

   Hint

   Think about how you roll out dough.

2. 2.

   Name one product produced via extrusion.

   Hint

   Consider common shapes we see.

3. 3.

   What does the rolling process do to metal?

   • Thickens the metal
   • Reduces the thickness
   • Increases ductility

   Hint

   Remember what happens when dough is rolled.

4. 4.

   True or False: Extrusion can only create round shapes.

   • True
   • False

   Hint

   Consider the diversity of shapes you see in structures.

5. 5.

   Design an aluminum frame structure and discuss how rolling and extrusion can be effectively used in its production.

   Hint

   Consider the required dimensions and shapes for strength in engineering.

6. 6.

   Investigate the impact of rolling and extrusion on aluminum waste reduction in construction practices.

   Hint

   Think about how efficient shaping technologies conserve materials.
