1. Aluminum extrusion profile
can play a role: Solve the metal stress generated in the process of extrusion, control the size of aluminum extrusion.
2. Extrusion straightening: Straightening is a very important link caused by aluminum extrusion profile twists and turns. The straightening industry must pay attention to the strength used in the straightening process. If the straightening strength is too large, it may cause deformation, closure, orange peel, etc. If the strength is too small, the profile will not be straightened, causing zigzag.
3. Extrusion rack: This part is also important. After sawing off a certain length of aluminum extrusion profile, the aluminum extrusion will be loaded. At this point, the framer will notice: whether it is large material or small material, is the material with pipe material or flat mold pulled out? Separately, the two ends of the lifting frame of large materials and pipeline materials are not easy to cause twists and turns, but small materials and surface die pulled out of the material, it is easy to raise the two ends to cause twists and turns, at this time, the two ends should be gathered to one side of the hoisting frame. However, some aluminum extrusion profiles, such as louvers, windows, pressure shrouds, etc., must be placed on the aging profile before being fitted into the frame. High quality aluminum sliding door should have a certain weight, smooth and no vibration.
