Calorimetric analysis, commonly known as the extrusion triple temperature
Aluminum bar temperature Exit temperature Extrusion temperature Tractor speed Extrusion rod speed Die temperature Charge barrel temperature Hardening temperature (temperature difference) Alloy pattern Ageing Reaching of physical properties of the metal Completion rate Productivity Calorimetric analysis Aluminum tapes and rods need to be heated up before extrusion to reach close to the solvus temperature so that the magnesium and magnesium inside the rods can be melted and flow uniformly through the aluminum material. flow evenly in the aluminum material. When the aluminum bar is put into the extruder, the temperature does not change much and is represented by a horizontal line in the graph.

When the extruder is started, the extrusion rod's huge push force to soften the aluminum material by the die hole extrusion, produce a great touching force, this touching force into temperature, make the extrusion of the profile temperature over the melting line temperature, at this time and magnesium melting, to all around the flow, very unstable. The temperature increase must not be higher than the solidus temperature, otherwise the aluminum will melt, and the profile can not be formed.
Aluminum bar temperature Aluminum bar temperature should be maintained between 400-540°C (6xxx series aluminum alloy as an example), is 470-500°C. Too high will cause tearing phenomenon, too low will reduce the extrusion speed (because the aluminum material must be softened) extrusion friction will be converted into most of the heat, resulting in a rise in temperature. The temperature rise is directly proportional to the extrusion speed and pressure.
