How to create your own branded vacuum flask from scratch. Choosing a factory, artwork requirements, sample process, MOQ, packaging options, and what can go wrong. Written from a Yongkang factory perspective.

OEM — Original Equipment Manufacturing — in the drinkware context means you take an existing factory design and put your brand on it. You don't need to design anything. You pick a model from the factory's catalogue, choose your color, submit your logo, and the factory produces it with your branding.
This is the entry point for most importers, brand owners, and Amazon sellers. It's the lowest-risk, fastest way to launch a branded product. MOQ at Jupeng is 500 pieces per design — that's 500 units of one color, one logo combination.

The most important variable in your OEM flask is the design you choose. Once you've placed a bulk order, changing designs means a new mold deposit. So choose carefully.
Key considerations: What capacity do your customers need? 500ml is the universal bestseller — fits car cup holders, is the Goldilocks size for a full day. 750ml and 1L are growing, especially for fitness and outdoor.
Lid type matters more than most buyers realize. The leak-proof guarantee lives or dies with the lid design. Request a sample lid with a full stress test before approving.

The artwork submission process is where most OEM projects slow down. To avoid delays:
For silk screen printing: submit AI, EPS, or PDF vector files. Minimum 2pt stroke width. Full CMYK color breakdown for each color. We'll return a print layout on the bottle outline within 24 hours.
For laser engraving: any format works since we convert to our laser software. Higher contrast logos work best.
For full-color heat transfer: minimum 300 DPI bitmap or vector. Provide a complete color profile.

Ordering a sample is non-negotiable before bulk production. It's the only way to verify color, logo placement, lid function, and packaging before committing to 500+ units.
Our sample process: you confirm the model, color, capacity, and send your logo. We produce one or two samples in 7–10 business days and ship DHL/FedEx Express to your door.
Sample cost is at manufacturing cost — typically $15–40 per sample depending on complexity. 100% refundable against your first bulk order of 1,000+ pieces.
