The wall thickness of the aluminum tube is uneven

The wall thickness of the aluminum tube is uneven because:

The centers of the extrusion barrel, extrusion shaft, extrusion needle, and mold are not consistent and need to be adjusted.

The ingot wall thickness is uneven or the cutting angle is too large, so you need to pay attention.

The extrusion shaft and extrusion needle are bent and need to be corrected and aligned to the center.

The extrusion barrel is too worn, and the diameter difference between the working part and the non-working part is too large, so it needs to be updated.

The gaps between the extrusion barrel, die, and extrusion pad are too large and need to be repaired.

The equipment is out of adjustment, the screws are not tight, the upper and lower centers are twisting, and the equipment needs to be adjusted.
