Umbrella type
5-Fold Umbrella
Five-section shaft giving the shortest folded length, around 20 cm. Tube tolerances and rivet consistency become critical because each extra section adds a joint and a failure point.
Structure
The 5-fold is the extreme of the compact family: five shaft sections and ribs that fold three times, giving a folded length around 20 cm that fits a coat pocket. Each section is thinner and shorter than on a 3-fold, and the shortest rib section is only a few centimetres long. That is what makes this the hardest folding frame to build consistently: tube ovality, swage depth and rivet hole pitch all sit on tighter tolerances, and a single out-of-tolerance joint makes the whole umbrella stiff to open or impossible to nest. Windproof spring joints are often specified here, because a thin frame has less margin against gusts.

Assembly flow & quality control points
- 1
Shaft section preparation
Supply chain / partnersTube sections are cut, swaged, punched and finished, then deburred and cleaned. Section fit is verified dry before any mechanism goes in. Four joints on five thin-walled sections; ovality and dent damage are checked on every section, not sampled.
Quality control points
- Section dimensions · Caliper + tube gauge per drawing · First article + 1 pc per 2 h
- Telescoping smoothness · Manual extend / retract x10 · 100%
- Coating / corrosion · Thickness gauge; neutral salt spray per buyer spec · Per order
- 2
Top notch & main rib riveting
Supply chain / partnersThe top notch is riveted to the main ribs. Slot pitch and rivet tightness decide canopy symmetry and whether ribs work loose in service.
Quality control points
- Rivet tightness · Visual + probe, no axial play, no deformation · 100%
- Rib symmetry / pitch · Visual on assembly jig, even spacing · First article + AQL per lot
- 3
Rib & stretcher hinge assembly
Supply chain / partnersMiddle and tail rib sections are hinged to the main ribs, stretchers are added, and windproof spring joints are fitted where specified. Joints must move freely without play. Three rib joints per rib is the most a production frame normally carries; a tight joint here stops the rib nesting fully.
Quality control points
- Joint freedom · Manual swing at each joint, no binding · 100%
- Joint play · Manual axial check, no looseness · 100%
- Rivet count per rib · Count against BOM, no missing joint · 100%
- 4
Runner & hubs on shaft
Supply chain / partnersThe mid hub, lower runner and any latch or catch parts are assembled onto the shaft in the correct order. The shortest runner stroke of any folding type, so the catch and the runner stop are set from the same datum.
Quality control points
- Runner travel · Manual slide over full stroke, no binding · 100%
- Latch engagement · Functional check: holds open, releases on demand · 100%
- 5
Handle assembly
Supply chain / partnersThe handle is fitted to the shaft and secured. Shortest handle of the family; grip length is limited by the folded bundle, so soft overmould is used to keep it comfortable.
Quality control points
- Handle retention · Static pull test; reference 150 N per GB/T 23147-2018 · 5 pcs per batch
- Grip alignment · Visual: handle axis in line with the shaft · 100%
- 6
Canopy cutting, printing & sewing
Supply chain / partnersPanels are cut, printed and sewn, and the seams are waterproofed. Stitch holes that are not sealed are the main source of canopy leakage.
Quality control points
- Logo position per panel · Visual against approved pre-production sample · Per lot, AQL 2.5 (ISO 2859-1 general level II)
- Seam leakage · Spray / shower test per ISO 4920 or buyer method · 5 pcs per batch
- Colour match · Compare to approved swatch under D65 light · Per dye lot
- 7
Canopy mounting on frame
Supply chain / partnersThe canopy is positioned on the frame, tied or stitched to the rib tips and tensioned evenly. Uneven tension shows as a sagging or twisting canopy.
Quality control points
- Canopy tension & symmetry · Visual in open position, no sag, no twist · 100%
- Canopy attachment · Pull check at each rib tip, no pull-off · 100%
- 8
Ferrule & rib tip caps
Supply chain / partnersTop ferrule and rib tip caps are fitted. Tip caps stop the rib ends puncturing the canopy and remove sharp points.
Quality control points
- Tip cap retention · Pull test to agreed spec, no pull-off · 5 pcs per batch
- Sharp points · Visual / radius check, no sharp tip exposed · 100%
- 9
Function & water test
Supply chain / partnersEvery umbrella is cycled, then samples are run through wind, shower and corrosion checks. Compact frames are checked for full nesting after the cycle run, since joint wear shows up first as a bundle that will not close fully. Function defects are treated as AQL 0.
Quality control points
- Open / close cycling · Cycle to buyer spec, no sticking, no latch or rib failure · 100% quick cycle + 5 pcs per batch full cycle
- Shower / water repellency · Spray test per ISO 4920, no drips inside · 5 pcs per batch
- Wind resistance · Fan or wind tunnel at agreed speed, no breakage, inversion recovers · Per order
- 10
Appearance inspection, folding & packing
Supply chain / partnersFinal appearance check, the umbrella is folded, sleeved, bagged and cartoned. Folding is done on the standard fold pattern so the canopy does not crease along new lines in the carton.
Quality control points
- Appearance & workmanship · Visual: no coating damage, no burr, no stain · Per lot, AQL 2.5 (ISO 2859-1 general level II)
- Packing quantity & marks · Count and carton mark check · Per carton
