By the Numbers

Shenzhen vape factory, in practical terms

Shenzhen is where most of the world’s vape hardware is engineered and assembled, and AISILE operates inside that supply base rather than sourcing from it. The difference shows up in the details: a change to an enclosure, a coil or a carton is answered by the production team, not relayed to a third party.

What the operation looks like in numbers: more than 5 million units of monthly production capacity, wholesale customers in over 50 countries and regions, and a standard 7–15 day dispatch window for wholesale programs. Custom programs run 7–15 days for sampling and 15–30 days for bulk production once the sample is approved.

What the factory controls directly

• Tooling and enclosure work — colour matching, logo printing, laser engraving and UV coating are handled on our own lines, so a branding change does not become a separate supplier round trip.
• Flavour development — a library of 2,000+ formulations, plus exclusive blends developed to order.
• Four inspection gates — incoming components, in-process draw and leak checks, final inspection against the approved sample, and pre-shipment verification of carton quantity and markings. A third-party inspection arranged by the buyer is welcome at the final gate.
• Export paperwork — technical file, test reports and labelling inputs for TPD, MHRA, CE and FDA submissions. The notification or authorisation itself is held by the brand owner in that market, not by the factory.

What to ask any Shenzhen vape manufacturer

Six questions separate a factory from a trading company: which production lines run your model, who signs the sample you approved, what happens to a failed batch, what the carton configuration is, whose name appears on the export documents, and what the factory refuses to change about the design. A supplier that answers all six in writing is the one worth a first order.

For how a program runs, the OEM/ODM manufacturing process sets out sampling, lead times and what to send for a quote. For the current range and its specifications, see the product catalogue.

Why a Shenzhen vape manufacturer can move faster

The reason most vape brands end up working with a Shenzhen vape manufacturer is not labour cost — it is proximity. A single device brings together a lithium cell, a PCBA, a moulded enclosure, a mouthpiece, a coil and a filled e-liquid chamber. In Shenzhen and the surrounding Pearl River Delta, every one of those supply links sits within a few hours of the assembly line, and most within the same industrial belt.

That density changes three things a buyer feels directly:

• Iteration speed — a sample revision that would need a shipment from three suppliers elsewhere is a same-week errand here. It is why sampling can run 7–15 days rather than a month.
• Component substitution — when a cell or a coil spec is unavailable, a Shenzhen vape manufacturer has alternatives that can be tested and validated without redesigning the device.
• Documentation access — the test houses that issue UN38.3, IEC 62133 and emissions reports are local, so the paperwork for a market notification is a scheduled task rather than a logistics project.

The same density has a downside worth naming: it is also why so many suppliers in this city describe themselves as a Shenzhen vape manufacturer when they are assembling from someone else’s components. Proximity to the supply chain is not the same as control over it. The test is whether the supplier owns the process between the components and the carton — incoming inspection, in-process checks, final inspection and a batch record — and whether you are allowed to watch it happen at the pre-shipment gate.

That is the standard AISILE works to, and the vape OEM manufacturer page sets out the twelve questions worth asking any Shenzhen vape manufacturer before you place a first order.

This site is maintained by the AISILE export team. AISILE is a vape hardware manufacturer with 5M+ units of monthly production capacity (2026), active wholesale customers in more than 50 countries, and a standard 7–15 day dispatch window for wholesale programs. The products featured on this site come from our own production lines, and the specifications published here are checked against factory datasheets before they appear on any product page.

How we verify what we publish

• Product specifications are cross-checked against factory datasheets and current production batches.
• Puff counts, e-liquid volumes and battery ratings come from manufacturer test data, not marketing estimates.
• OEM/ODM capabilities, minimum order quantities and packaging options are confirmed with the production team before being described in any guide.
• Market-specific compliance notes are reviewed before orders are confirmed, and buyers are always advised to verify local requirements.
