Causes of surface corrugation defects on aluminum profile:
1. the design of the length, proportion or cavity size of the aluminum profile extrusion die is seriously wrong, and the flow ratio is seriously disturbed.
2. aluminum extrusion dies work with angle of obstruction and angle of flow.
3. the difference of the drop ratio of the upper and lower die in the aluminum extrusion die.
4. die die work with parallel aluminum extrusion, a horn mouth.
5. the die resistance of the aluminum profile extrusion die is high on the flow table, blocking the work out with the material or drainage slot (size, depth, position).
6. aluminum profile extrusion die work belt outside the empty knife is too few, even does not have (the electric spark not to hit well) or too big (the work belt does not support to crack the distortion).
7. the new die or repaired aluminum extrusion die is difficult to produce because of the uneven grit, polishing and uneven working band.
8. part of aluminum extrusion work with oil.
9. the support pad is too small to hinder.
10. aluminum tail waves appear around 1m (V3 volume aluminum press).
