Factory and capacity

Item	Figure	What the figure covers
Plant area	3,500 m²	Total floor area in Dongguan (Dongcheng Street), covering workshop, warehouse and office. Check it on a live video walk-through or a factory audit.
Product range	100+ product types; 21 models already on tooling	“On tooling” means the mould already exists, so the model can be ordered without new mould cost.
Monthly capacity	3 production lines, 27 machines, 300,000+ pcs	Capacity at the current shift pattern. It is not a guaranteed monthly output for a specific order.
Quality control	4 QC staff across 2 inspection lines	Incoming material check, in-process inspection and final test before packing.

Order terms and lead times

Term	Figure	When the clock starts
Minimum order	50 pcs per model	Includes custom logo, colour, material or packaging on any of the 21 models already on tooling.
Sampling	7–10 working days	Counted from the confirmed drawing, not from the first message.
Mass production	7–12 days	Counted from sample approval.
Packing and final inspection	3–5 days	After production, before the goods leave the plant.
Shipping term	FOB Shenzhen	Other terms are quoted per order; we do not publish prices.

Measured specifications

Model	Size	Weight	Magnet
OX-3	58 × 4.5 mm	25 g	N52 · 4,100 GS
CX-5	58 × 3.8 mm	18 g	N52 · 4,100 GS
X7	60 × 5.8 mm	21 g	Not published
X39	53.7 × 32.5 mm	42 g	N52 grade; gauss value not published

Magnet strength is measured by our own QC on OX-3 and CX-5 only. It is not a third-party laboratory report. Other models have no published magnet figure — ask for the measurement with your sample. X23 is a car-use phone stand with an SK7 hinge cycle-tested beyond 6,000 open-close movements.

Intellectual property

Item	Registration	Scope
Granted patents	8 (5 design patents + 3 utility models)	Granted by CNIPA and held solely in the company’s own name. The certificate scans are on the homepage under certificates and registrations; ask for the originals to check any number.
Registered trademark	No. 80143576, Class 9	Covers phones, phone cases, earphones, USB cables, sensors and batteries.
Copyright registration	国作登字-2024-F-00271084	Artwork copyright for the Feigangxia logo.

Certificates we do not hold

We do not hold CE, RoHS, REACH or SGS certificates, and we do not claim FCC, MFi or MagSafe licensing. Stating this plainly is more useful to a buyer than a logo wall.

What we can do: arrange the testing your destination market requires as part of an order, and quote it together with the goods. Ask any supplier for the certificate number and issuing body, then check it against the exact product you are buying.

What we do not publish, and why

Prices. Every quote depends on quantity, material, logo method and packaging, so a public price list would be wrong for almost every order.
Customer names. The homepage brand line describes supply history only; it is not an endorsement or a licence.
Specifications we have not measured. Where a model has no published size, weight or magnet figure, the cell stays empty and the drawing is sent with the sample instead.
Certificates we do not hold. See the section above.

How to check these claims yourself

Ask for a live video walk-through of the plant — mould shop, injection machines, assembly line and packing area — instead of a photo set.
Order a sample against the drawing, then measure the magnet strength and hinge feel yourself.
Verify the patent, trademark and copyright numbers in the public registers (CNIPA and the copyright registry) before you rely on them.
Before paying the balance, ask for a video of your own batch being tested, not a staged demo.
