Aluminum rod problem

The surface of the aluminum rod has mechanical damage.

This is because the surface of the aluminum rod is bumped, scratched and scratched during the operation and transportation of each process.

The surface of the material frame, material rack and wire dropper is not smooth, which scratches and bruises the surface of the aluminum rod.

Therefore, the aluminum rods should be handled with care, carefully operated, sharp edges polished, or wrapped with soft materials and pads.

The aluminum bar has a jump ring, which may be because the working taper of the roll is too large, resulting in a large vertical split, the working area of the roll is too smooth, and the processing rate is too large.

The working cone angle of the aluminum rod needs to be polished, polished with coarse gauze, or washed with oil to increase the friction of the surface.

The surface of the aluminum rod has corrugations, which may be because the die hole sizing area is too short when the processing rate is 20%. It is necessary to adjust the pass power and choose a suitable die.

If the working cone angle of the roll is too large, it will also cause ripples on the surface of the aluminum rod. The working cone angle of the roll needs to be adjusted.

The size of the aluminum rod does not match, which may be due to errors in the mold size measurement. You need to choose a suitable mold.

The power added per pass is too large, and the size is too small, so the power added per pass needs to be adjusted.
