The manufacturing process of a sun umbrella includes material selection, rib fabrication, canopy cutting and sewing, assembly, surface treatment, quality inspection, and packaging. For example, the ribs may be made of aluminum alloy/fiber, the canopy of which uses sun-protective materials. After sewing, the umbrella is assembled, coated to enhance performance, and finally inspected and packaged.
The main manufacturing process of a sun umbrella includes three stages: material pretreatment, precision machining, and performance testing. The ribs are made of aluminum alloy tubing, which is cut, bent, and welded, and the surface is anodized to improve corrosion resistance. The canopy fabric undergoes UV coating or silver coating treatment, and then CNC cutting and double-stitching ensure secure edges. During assembly, anti-loosening rivets are used to fix the ribs and canopy, and finally, wind resistance (≥8 levels) and waterproofing (500mm/h) tests are conducted.
