Q:

Do your disposables support automatic preheat for thick extracts?

AF02, H73,H85 and H91 series blank disposables integrate built-in automatic preheat circuits, eliminating the need for separate preheat batteries for live resin and rosin products.

Q:

How can I test hardware compatibility with my oil formula?

We provide free hardware sample kits including C-series cartridges and H-series disposable pens for US brand buyers to test with live resin, rosin, delta 8, delta 9 or CBD oil before placing bulk wholesale orders.

Q:

Are your empty vape devices compliant for US state distribution?

All AFJ hardware are blank, oil-free empty vaporizer components with no pre-filled concentrates. As pure hardware suppliers, our products meet US empty vape device compliance standards for delta 8, delta 9 and CBD extract filling and wholesale distribution.

Q:

Do you offer custom private label hardware for US brands?

Yes, full OEM/ODM customization is supported, including custom body colors, UV full-print graphics, laser engraved logos, personalized childproof packaging and adjustable tank capacities from 0.5ml to 3ml. We accept flexible low MOQ for startup US extract brands.

Q:

What’s the difference between copper-free full ceramic and regular cartridges?

AFJ C32 adopts 100% copper-free full ceramic structure with pure ceramic central post, no metal contact with oil. Standard carts use metal posts that oxidize with terpenes, causing metallic off-flavor in live resin and rosin products.

Q:

Can one disposable model fit all oil types (live resin, delta 8 distillate, CBD)?...

Slim low-wicking disposables (H78/H80) work well for thin delta 8 and CBD distillate only. For live resin and rosin oil, select models with large-pore dual ceramic coils and built-in preheat function (H91, AF02) to ensure stable oil supply and consistent vapor output.

Q:

Which hardware works best for ultra-thick solventless live rosin oil?

Full ceramic atomizer hardware with oversized oil inlet holes is required. Our AFJ C32 510 cartridge and AF02 dual-channel disposable pen are purpose-built for high-viscosity cold-pressed rosin, with anti-clog ceramic cores and preheat support to avoid dry hits. Partial ceramic carts are not recommended for pure live rosin formulations.

Q:

What vape hardware works best for rosin?

Rosin is one of the thickest cannabis extracts and requires vape hardware with fast oil absorption and stable heating. Ceramic core hardware performs best because its porous structure allows rosin to penetrate the heating area quickly, reducing the risk of clogging and dry hits.

Q:

Why does my disposable vape clog after sitting on shelves?

Clogging usually happens because the coil inside the device cannot absorb thick oil fast enough after a period of storage. When the oil settles, traditional coils struggle to re-saturate. Ceramic cores solve this by allowing faster oil wicking even after long shelf time.

Q:

Is 2ml or 3ml better than 1ml for dispensary sales?

Yes. 2ml and 3ml disposables provide longer usage cycles, better retail value for consumers, and fewer return issues for dispensaries. Larger reservoirs are now preferred by many US cannabis brands filling locally.
