Aluminium tube aluminum tube should be properly increased due to the poor performance of the confluence of the shunting ribs. The length of the rib and the outer surface & aluminum tube ribs and the confluence of the ribs and the increase of the compression ratio can be used to solve the change in the pressure of the aluminum tube die. The flow resistance is adjusted by changing the length of the flat section of the die; the aluminum tube can be selected at different stages of the mold design to change the extrusion pressure & aluminum tube but must pay attention to the compression ratio of the head compression ratio to the extruder screw Adapted; the melt pressure can also be varied by changing the formulation & aluminum tube to adjust the extrusion process parameters & the aluminum tube to increase the perforated plate.
The cooling rate of aluminum tube aluminum tube sizing die & aluminum tube cooling water temperature often does not cause enough attention. The function of aluminum tube cooling water is to cool and shape the macromolecular chain of aluminum tube in time to achieve the purpose of use.
Aluminium tube aluminum tube die section design is unreasonable & aluminum tube, especially the distribution of internal ribs and interface angle treatment & aluminum tube aluminum tube will cause stress concentration phenomenon & aluminum tube needs to improve design and eliminate the right angle at the interface And sharp corners.
