Conditions to be satisfied before aluminum extrusion：
During the aluminum extrusion process, the friction between the extruder and the extruded aluminum alloy increases the pressure consumption and the deformation of the aluminum alloy.
Therefore, the extruding method of the selected aluminum profile should be under the conditions
set to ensure that the minimum friction in the choice of extrusion methods, should meet the main
given conditions include:
1. The possibility of squeezing the process that the equipment has
2. The plasticity of the extruded metal in the extruded state
3. Meet the quality requirements of extruded aluminum profiles
