Exploring Metal Forging Techniques

What is the primary purpose of heat treatment in metal forging?

• To increase the metal's weight

• To enhance the metal's mechanical properties

• To change the metal's colour

• To reduce the metal's density

Which of the following is a common application of forged metals?

• Plastic packaging

• Aerospace components

• Textile manufacturing

• Paper production

What is a key safety measure in metal forging?

• Wearing sandals

• Using protective eyewear

• Working with bare hands

• Ignoring safety protocols

In drop forging, what is used to shape the metal?

• A hydraulic press

• A hammer

• A drop hammer

• A rolling mill

What distinguishes pressure forging from other forging methods?

• It uses low pressure

• It uses high pressure

• It does not use pressure

• It uses only manual force

What is the main characteristic of upset forging?

• Lengthening the metal

• Reducing the metal's diameter

• Increasing the metal's diameter

• Flattening the metal

Which heat treatment process involves heating and then cooling the metal slowly?

• Quenching

• Annealing

• Tempering

• Hardening

What is a common use of forged steel?

• Making glass bottles

• Constructing bridges
