Handmade Silk Fan Quality Inspection FAQ
What defects do you check on a handmade silk fan face?
Check the silk under even light for pulls, snags, thin spots, and uneven dyeing, then examine printed or hand-painted motifs for blurring and registration errors where colors should meet. Inspect the mount line where silk meets the outer rib for fraying, glue bleed, or lifted edges, and open the fan to confirm the face lies flat without puckering. A dry white-cloth rub test across the dyed face flags poor dye fixation. (Source: eastfanart silk fan inspection framework, 2026)
How do you test the rivet and hinge of a folding silk fan?
Open and close the fan 20 to 30 times and feel for roughness, catching, or resistance at the pivot. The rivet head should sit flush and smooth on both faces with no sharp burr, the hinge plates should align without offset, and a half-open fan should hold its position instead of collapsing under its own weight. Lateral wobble at the pivot when you gently wiggle the open fan is a fail signal. (Source: eastfanart pivot assembly test standard, 2026)
How do you inspect bamboo or wood ribs on a handmade fan?
Sight down the closed fan at eye level to catch any rib bowing out of line, then run a fingertip along both edges of each sampled rib to feel for rough sanding or splinters. Check that the outer ribs match the inner ribs in width, confirm tips are clean and unchipped, and examine the head plate under bright light for hairline cracks near the rivet hole, which signal early hinge failure.

What open-close cycle test should a buyer run on silk fans?
Run a minimum 20-to-30-cycle open-close test on every sampled fan, because hinge and rivet faults appear within the first few dozen cycles. Add a half-open hold test to verify the fan stays put without collapsing, and repeat a short cycle test after the visual passes to catch damage from handling during inspection. Fans that pass mechanical tests first, then visual checks, give the most reliable lot result. (Source: ISO, Standards Catalog, Quality Management and Testing, 2024)
What sampling plan should a wholesale buyer use for silk fan inspection?
Use an AQL-style random sample pulled across cartons, never from the top box only. For a 500-fan lot, check 20 fans and allow no critical defects plus a maximum of three major defects; for 2,000-fan lots, check 32 fans with up to four major defects; for 5,000-plus lots, check 50 fans with up to five major defects. Record every fault by zone — hinge, rib, silk, mount — with photos, so the report tells the supplier exactly which workshop step to correct.

Why do handmade silk fans need different inspection standards than machine-made fans?
Machine fans repeat the same tolerance on every unit, while handmade fans vary naturally in dye tone, rib width, and tension from artisan to artisan within one carton. Slight tonal variation is a quality marker of handmade silk, but hinge fractures, torn fabric, splintered ribs, and lifted mount lines are genuine defects. Define the acceptance criteria by zone with the factory before production so craft character is preserved while structural reliability is guaranteed.

How does the inspection record relate to import documentation?
Keep lot number, fiber content, country of origin, inspection date, and results on a single certificate so the QC record doubles as the customs-ready file. U.S. import guidance requires accurate country-of-origin and fiber content declarations for textiles and craft goods, and an aligned inspection record survives desk audits on either side of the border.
