[0002] Aluminium alloy extrusion is a common metal processing method, and the principle of aluminium alloy extrusion can be simply summarized as thermal expansion and contraction and metal flow. Thermal expansion and contraction refers to the fact that, during heating, metal materials will expand due to the increase in temperature, and will shrink during cooling. By adjusting the shape and size of the die, the expansion and contraction of the metal material can be controlled to obtain the desired profile. Metal flow refers to the fact that, after heating, the internal structure of the metal material changes, making it have good plasticity and deformability. During extrusion, the metal material is subjected to pressure and flows into the desired shape aperture under the guidance of the die, forming a profile.
