Questions and Answers

What happens after the die has been closed and locked in the die casting process?

  • The air in the die escapes through vents, and excess metal is removed from the cavities.
  • The die is cooled down to facilitate easier ejection of the casting.
  • Molten metal is delivered to a pump/plunger and driven quickly through the feeding system. (correct)
  • The die is immediately opened to check the quality of the casting.

    • What is the key difference between die casting and permanent mould casting?

  • Die casting involves metal flow at high velocities induced by pressure, while permanent mould casting depends on gravity for mould filling. (correct)
  • Die casting does not involve the use of a pump/plunger, unlike permanent mould casting.
  • Die casting produces shapes with less complexity than permanent mould casting.
  • Die casting uses single-use metal moulds, while permanent mould casting uses reusable metal moulds.

    • What is done while the casting die is open in the die casting process?

  • The excess air in the die is removed through vents.
  • The molten metal is poured into the die cavities.
  • The solidified metal is inspected for any defects.
  • The die is cleaned and lubricated as required. (correct)

    Study Notes

    Die Casting Process

    • After the die has been closed and locked, molten metal is injected into the die cavity under high pressure to produce a casting.

    Die Casting vs. Permanent Mould Casting

    • The key difference between die casting and permanent mould casting is the use of pressure: die casting uses high pressure to inject molten metal, whereas permanent mould casting uses gravity to fill the mould.

    Die Casting Process (Open Die)

    • While the casting die is open, the die is sprayed with a lubricant and the previous casting is ejected.

    Complexity of Die Casting Shapes

    • The use of high pressure and rapid injection of molten metal allows die casting to produce more complex shapes compared to permanent mould casting.

    Advantages of Die Casting

    • One advantage of die casting over permanent mould casting is its ability to produce castings with a high degree of accuracy and precision.
