[China Aluminum Industry Network] Extrusion and straightening: Straightening is a very serious link caused by the profile, straightening work must pay attention to the intensity of straightening used, if the strength is too large, it may cause deformation, shrinkage, orange peel, etc. of the profile. If the strength is too small, the profile will not straighten, causing bending. Squeeze frame: This section is also very important, after sawing out the fixed length, aluminum will be framed, this fashion frame worker should pay attention to: This material is an oversized or small material, is with pipe or plane Mold pulled out of the material? In general, the material and the tube are not easily bent at both ends of the frame. However, when the material is pulled out from the small material and the planar mold, the two ends can easily be bent. At this time, it should be from the two ends to the middle. Move closer to frame the material. However, even if some profiles do not work, such as louvers, windows, lids, etc., they must be placed on time-efficient profiles and lifted into frames. Surface treatment: The billet is aged, the hardness is up to standard, and the profile is not so easily bent. However, when it is put on the shelf, it is necessary to pay attention to it. When both ends are raised, try to avoid vigorous fluctuations. The vigorous fluctuations will also cause aging aluminum profiles. A certain amount of bending.
