Total questions: 15
Worksheet time: 8mins
What is die casting primarily used for?
Creating high volumes of complex components
Creating small volumes of simple components
Welding metal parts together
Cutting metal into various shapes
Die casting is the metal equivalent of which process?
Forging
3D printing
Injection moulding
CNC machining
How is molten metal introduced into the die in die casting?
Drawn into it by vacuum
Forced into it by gravity or pressure
Injected by robotic arms
Poured by hand
What happens to the molten metal in the die before it is ejected?
It is heated further
It is compressed further
It is stirred continuously
It is allowed to cool
What are parting or split lines in die casting?
Cracks due to metal fatigue
Decorative features of the component
Lines produced because the mould halves
Marks left by cutting tools
What causes ejector pin marks in die casting components?
Excess material leaking out of the mould
The material isn't fully cooled before being ejected
Improper placement of the component in the mould
Use of excessive force during ejection
What is the role of pressure in die casting?
To remove impurities from the metal
To polish the finished component
To heat the metal
To force the molten metal into the mould
Why is high accuracy mentioned as a feature of die casting?
Because the process is fully automated
Because the components require no finishing
Because it uses high-quality metals only
Because of the precision of the moulds
What is the significance of cooling in the die casting process?
It prevents the mould from overheating
It hardens the metal, forming the component
It cleans the surface of the component
It speeds up the production process
How does die casting compare to injection moulding in terms of materials used?
Both use a combination of metals and plastics
Die casting uses metals, while injection moulding uses plastics
Both use exclusively high-grade alloys
Die casting uses plastics, while injection moulding uses metals
What allows for the high degree of accuracy in die casting?
The design of the die
The temperature of the molten metal
The skill of the operator
The quality of the metal
Why are high volumes of components typically produced in die casting?
Because the materials are rare
Because it is a requirement of the process
Because it is a very slow process
Because the setup costs are high
What is a key identifying feature of components made by die casting?
They have no visible marks
They are coated in plastic
They are always metallic
They have parting or split lines
Why might ejector pin marks be considered a drawback in die casting?
They may require additional finishing
They are difficult to remove
They indicate the component is not durable
They signify the use of low-quality metal
In what way is gravity used in some die casting processes?
To cool the components more quickly
To separate impurities from the molten metal
To increase the pressure inside the mould
To force the molten metal into the mould
