Scratches and scratches on the outer surface of aluminum alloy pipes

The scratches and abrasions on the outer surface of aluminum alloy pipes may be caused by scratches or sharp edges on the aluminum mold workpiece, which need to be polished.

The work belt is stuck with metal and needs to be cleaned off.

Excessive lubricant has fallen into the squeeze barrel and needs to be cleaned out.

There are cracks on the surface of the aluminum tube because the heating temperature of the ingot is too high or the extrusion speed is too fast. The extrusion speed and temperature need to be adjusted.

The surface of the aluminum tube may be dented or scratched. This may be caused by carelessness during various operating procedures or transportation, resulting in artificial bumps collisions, and scratches, so please handle it with care.

The places where the material racks, material baskets, discharge tables, etc. come into contact with the aluminum tubes are not covered with soft materials, so there will be bumps and bruises.
