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
