The scrapping of
industrial aluminum profiles caused by bending is very regrettable and not worth it, so let's see how to reduce bending scrapping.
1. Extrusion straightening: Industrial aluminum profiles if you want to bend so in the extrusion straightening link is very important, straightening workers must pay attention to the strength used for straightening, too much force may produce the profile closing, deformation, orange peel, etc., the force is too small will produce the profile is not straightened, resulting in bending.
2. Extrusion framing: After sawing industrial aluminum profiles by size, it enters the framing link, which is also very important. The fashion framer should pay attention to it. Generally speaking, aniseed and pipe material lifting either ends of the frame is not amiable to cause winding, but small material and surface mold pulled out of the stuff, lifting both ends is easy to cause bending, then it should be moved from both ends to the middle of the frame. But some profiles even if this is not enough, such as: window, louver, gland, etc., you must put this kind of material on the aged profile and then lift to the frame.
3. Surface treatment shelf: Billet after aging, hardness has reached the standard, industrial aluminum profiles is not so easy to bend, but it is still necessary to pay attention to when the two ends of the lifting material, try to avoid up and down strong fluctuations, strong fluctuations will also cause certain bending of the aging industrial aluminum profiles.
