Q. What is Hot extrusion?

Hot extrusion is a hot working process, which means it is done above the material's recrystallization temperature to keep the material from work hardening and to make it easier to push the material through the die.

• Most hot extrusions are done on horizontal hydraulic presses that range from 230 to 11,000 metric tons . Pressures range from 30 to 700 MPa

• oil or graphite is used for lower temperature extrusions, or glass powder for higher temperature extrusions.

• The biggest disadvantage of this process is its cost for machinery and its upkeep.
