Worksheet time: 60secs
What is the main principle of casting?
Pouring molten material into a mould to form a shape
Shaping metal using compressive forces
Machining a solid block
Cooling metal sheets rapidly
Which of the following is NOT a type of casting?
Sand Casting
Investment Casting
Die Casting
Drop Forging
What is the main function of the 'riser' in a casting mould?
To feed molten metal and compensate for shrinkage
To create the shape of the product
To vent gases from the mould
To control the metal flow rate
In sand casting, what is the difference between green sand and dry sand?
Green sand is more expensive
Green sand is used for large castings only
Green sand contains moisture, while dry sand is baked
Dry sand cannot be reused
What part of the mould is referred to as the 'cope'?
The lower half of the mould
The upper half of the mould
The molten metal reservoir
The gating channel
What is the function of the gating system?
To control temperature
To guide molten metal into the mould cavity
To remove flash from the product
To cool the mould faster
Which of the following is an advantage of casting?
Produces complex shapes
Creates very low strength parts
Generates minimal waste
Requires no machining afterwards
Which of the following materials is most commonly used in casting?
Cast Iron
Plastic
Titanium Alloy
Carbon Fiber
Which UK regulation covers the safe handling of hazardous substances during casting?
COSHH
ISO 9001
HASAWA
PUWER
What is one key difference between forging and casting materials?
Forging materials are chosen for fluidity
Casting materials are selected for strength
Forging materials resist deformation
Casting materials are better for complex shapes
Which of the following best describes the 'sprue' in the gating system?
A. A reservoir that stores molten metal
B. A vertical channel that directs molten metal
C. A vent hole for gases
D. A part used for cooling the mould
Why is health monitoring important in foundries?
To detect early signs of respiratory issues from dust and fumes
To check product quality
To monitor temperature of molten metal
To track production speed
