4.3. Casting

Try these first

1. 1.

   Define casting in manufacturing.

   Hint

   Think about how shapes are formed in manufacturing.

2. 2.

   What is sand casting?

   Hint

   Consider the material used for the mold.

3. 3.

   What is aluminum casting?

   • A process of forming aluminum sheets
   • A method for making complex shapes from molten aluminum
   • An alloying process

   Hint

   Think about how molds are used in shaping metal.

4. 4.

   True or False: Die casting is slower than sand casting.

   • True
   • False

   Hint

   Consider the speed and method of the process.

5. 5.

   Evaluate the trade-offs of using sand casting versus die casting for producing automotive parts.

   Hint

   Consider production speed, cost, and part complexity.

6. 6.

   Analyze how the addition of silicon impacts the casting quality of aluminum alloys.

   Hint

   Think about how different materials change the behavior of aluminum when melted.
