Recap metal forming

How many types of forming methods do we have?

• 2

• 3

• 4

The metal forming processes is divided in:

• hot, cold and warm processes

• forging, rolling and extrusion

• hot, cold and forging

In the hot working process:

• the temperature is BELOW the metal's melting point

• the temperature is ABOVE the metal's melting point (higher than the 60% of it)

• It's performed at room temperature

The translation of ROOM TEMPERATURE is

• temperatura calda

• temperatura ambiente

• temperatura fredda

What is FORGING?

How many types of forging processes do we have?

• Just one type

• We have two types: open die forging and close die forging

• We have three types:open die forging, close die forging and hand forging

Which types of metals can be forged?

• Just non ferrous metals in alloy form

• Just ferrous metals

• Any types of metals

What happens to the internal make-up of a metal when it's forged?

Explain the extrusion process:

How many types of extrusion process do we have?

• 1

• 2 (hot and cold extrusion)

• 3 (hot, cold and impact extrusion)
