Sleeving
Cells are sleeved automatically, which is what puts the printed wrap and the polarity marking on straight every time.
PUJIMAX ведёт сборку, тестирование и упаковку на площадке в Дунгуане; между входным контролем и запечатанной коробкой — четыре этапа проверки.
Критерии контроля и план выборки для вашей модели передаём вместе с предложением.

Компания зарегистрирована в Ваньцзяне (Дунгуань) с 2014 года и участвует в Кантонской ярмарке и HKTDC. Если для аудита поставщика нужны актуальные фото линий, численность или площадь — запросите, и мы пришлём датированную справку по площадке, а не цифру из профиля маркетплейса.



Так выглядит процесс на площадке в Дунгуане. На OEM-заказе ваш брендинг наносится на пятом шаге.

Cells are sleeved automatically, which is what puts the printed wrap and the polarity marking on straight every time.
The moulding area forms components to the shape the cell or charger housing needs.
Automatic liquid filling — the dosing step that decides whether cells in the same batch behave the same way.
Caps are seated and closed automatically, the seal that keeps the cell from leaking in a customer's device.
Parameters and logo are laser-engraved rather than printed, so the marking survives handling. This is also where your branding goes on an OEM run.
Сборка, тестирование и упаковка идут отдельными линиями, у каждой свой контроль качества, а не одна проверка в конце.
| Производственные линии | Мастера | Операторы | Контроль на линии |
|---|---|---|---|
| Assembly line 1 | 2 | 10 | 3 |
| Assembly line 2 | 2 | 6 | 4 |
| Test line 1 | 2 | 10 | 3 |
| Test line 2 | 2 | 10 | 2 |
| Packaging line 1 | 3 | 12 | 2 |
| Packaging line 2 | 2 | 10 | 1 |

The workhorse of the test line — every cell and charger is checked against its rated output.
Full-function test of a finished charger: each slot, the display and the charge behaviour.
Measures what a charger actually delivers under load, not just what it reads at idle.
Dielectric withstand testing on mains-input chargers, the safety check before a unit is packed.
Под эти этапы пишутся ваш план качества и критерии приёмки.
Cells, components and packaging checked against the approved specification.
Assembly parameters, polarity, welding and in-line function checks.
Capacity, charging behaviour and output verified against the specification.
Appearance, labelling, pack-out, sampling and shipping documents.
The exact coding method still requires company confirmation; this page shows the four buyer-facing checkpoints and deliverables.
Lock the model, revision, pack and inspection criteria.
Production and in-line checks stay attached to the lot.
Sampling, appearance and pack-out are signed off.
Specifications, declarations and transport files map to the order.
Состав документов зависит от модели, химии и рынка поставки. Ниже — что есть и что именно покрывает каждый пункт.
Nominal voltage, capacity and test method, dimensions, temperature range, pack count and carton data for the model you select.
We hold manufacturer declarations covering our battery families and map them to your exact model and market before you order.
Type-C lithium and CR123A shipments need model-specific UN38.3 and SDS. Tell us the model and how it ships and we prepare the set.
Scope is production and sales of precision hardware stamping parts. We do not present it as a battery manufacturing certificate.
Tell us the model, destination market and transport mode and we will list the available files, gaps and preparation route in the quotation.
