The extrusion aluminum heat sink box temperature is adjusted according to different products and unit pressure during operation. During the extrusion process, the temperature of the ingot in the deformation zone changes. With the completion of the extrusion process, the temperature in the deformation zone increases gradually and increases with the increase of the extrusion speed. Therefore, in order to prevent the occurrence of extrusion cracks, the extrusion speed should decrease gradually with the progress of the extrusion aluminum heat sink box process and the increase of the temperature in the deformation zone.
