Leaving Cert Engineering: Casting, forging & forming

How often Casting, forging & forming comes up on the Engineering papers, every year it was asked, and questions to try.

HL Asked on 1 of the last 9 Higher Level papers, most recently in 2024.

June 2028 is the first exam on the new Engineering course. These come from the 2016–2025 papers, so read them as a guide.

Casting, forging & forming, Higher Level(8 marks)

Quick ones on Casting, forging & forming.

(a)Why is a sand-casting pattern made slightly larger than the finished part?
  1. To make the mould easier to fill
  2. To allow for shrinkage as the metal cools
  3. To reduce the amount of metal needed
(b)Why are FCC metals such as aluminium easier to extrude than BCC metals?
  1. They are harder than BCC metals, so they resist tearing
  2. They have higher melting points, so they flow when hot
  3. More close-packed slip planes let them deform easily
(c)Deep drawing is used to make?
  1. Seamless cup shapes from flat sheet
  2. Solid parts from molten metal
  3. Long bars of constant cross-section

In sand casting, a core is used to?

  1. Feed metal to the casting as it shrinks
  2. Let gases escape from the mould cavity
  3. Form internal holes or cavities in the casting
Show the answer

Form internal holes or cavities in the casting

A core, usually of bonded sand, is placed in the mould so metal flows around it, leaving a hollow, e.g. the bore of a pump body. Risers feed and vent.
