It is very uneconomical to scrap the aluminum profile as soon as it is bent, and it is necessary to avoid such a thing. So, how to reduce or avoid the scrapping of aluminum profiles due to bending?

First of all, extrusion and straightening will cause the bending of aluminum profiles: straightening is a serious part of the bending of aluminum profiles. The straightener must pay attention to the force used for straightening. If the force is too large, the profiles may be deformed, closed, and orange. If the force is too small, the profile will not be straightened, resulting in bending.

Secondly, extrusion and framing will also cause bending of aluminum profiles: this link is also very important. After sawing to a certain length, the aluminum profiles will be framed. At this time, the framer should pay attention to: whether the material is large or small material, is it a pipe material or a material drawn from a flat die? Generally speaking, it is not easy to cause bending when the two ends of the large material and the material with the tube are lifted and framed, but the two ends of the small material and the material pulled from the flat die are easy to be bent. Move closer to lift and frame. But some profiles are still not enough, such as: shutters, windows and glands, etc., such materials must be placed on the aged profiles and then lifted into the frame.

Finally, the surface treatment will also cause the aluminum profile to bend: the billet has been aged and the hardness has reached the standard, and the profile is not so easy to bend, but you should pay attention when you put it on the shelf. When lifting the material at both ends, try to avoid strong fluctuations up and down. It will cause certain bending of the aged aluminum profile.
