Empty Aluminium Squeeze Tubes are generally made of 99% pure aluminum for squeezing and curling.

The production method of Empty Aluminium Squeeze Tubes is to punch a certain thickness of aluminum plate with a precision blanking punch, blanking into small round blanks, after annealing, and then impact extrusion on a 100-350T extruder to make the rounds The blank extends outwards into a tube along a certain length and diameter, and finally reaches a certain size. The formed aluminum tube must undergo heat treatment to eliminate the work hardening effect, so as to avoid cracking during extrusion and curling. Finally, paint and dry the inner wall of the aluminum tube, and perform decoration printing on the surface of the tube.
