Instructions:
  • Answer 17 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Molten metal flow down through.






2. Place a pattern in sand - make a gate - remove the pattern - fill mold with molten metal - allow solidification - and break away sand to remove casting.






3. Typically made of sand - plasters - ceramics - after solidification mold is broken up to remove casting.






4. Inserts made from sand that are placed in the mold to form hollow regions to define interior surface of the casting.






5. Supply additional molten metal to the casting during solidification. a.) Blind riser b.) Open riser






6. 1.) Evaporative- pattern Casting (lost foam process) 2.) Investment Casting.






7. Used to mold the sand into shape for the casting. Can be made from: a.) Woodb.) Plastic c.) Metal






8. Improved the overall casting process.






9. Made of two or more different materials - like sand - graphite - and metal.






10. Holds the mold and has two pieces: a.) Cope (TOP) b.) Drag (BOTTOM) c.) Cheeks (If more than two pieces are used)






11. Used for castings with internal cavities or passages Example: Engine blocks.






12. Molten metal is poured into.






13. Made of metals that maintain their strength at high temp. Used repeatedly - and castings can be removed easily.






14. 1.) Sand Casting 2.) Shell Molding 3.) Plaster- mold Casting 4.) Ceramic- mold Casting.






15. Channels that carry molten metal from the sprue to the mold cavity. a.) Gates are the inlets into the mold cavity.






16. A.) One- piece. b.) Split (two piece) c.) Match- plate.






17. 1.) Permanent- mold Casting 2.) Vacuum Casting 3.) Slush Casting 4.) Pressure Casting 5.) Die Casting 6.) Centrifugal Casting
