The main reasons for defects of aluminum profiles wave, twist and bend are as follows :
1. The unreasonable design of aluminum extrusion die working belt leads to uneven metal flow;
2. Extrusion speed is too fast or extrusion temperature is too high, resulting in uneven metal flow; 3. Dies cavities layout is not reasonable, resulting in uneven metal flow;
4. Guide is not suitable or not installed guide;
5. Lubrication is not suitable.

1. Correct the extrusion die working belt, make the metal flow uniformly;
2. Adopting reasonable extrusion process, on the premise of guarantee the outlet temperature by low temperature extrusion;
3. Reasonable design of aluminum extrusion die structure;
4. Configure the appropriate guide way;
5. Reasonable lubrication;
6. Use puller machine in extrusion processing.
