Silicone molds for gelatin gummies: early demold without stretch
Gelatin gummies are not pectin gummies. Gelatin is usually less sticky, so a 20A-30A tray that tears a pectin mascot may peel gelatin clean - and the same tray will still sag 0.5-1.5 mm at the edge if you skip the jacket, so outer-row 4 g pieces run 3-6% heavy. The gelatin-specific fail is early demold: a piece that looks set on the bench stretches or prints condensation if you peel too soon or store the tray cold and wet. Don't copy a pectin Shore-and-jacket spec onto gelatin without a formula test. RUUIPON pours platinum RTV gelatin trays in Bao'an since 2018: resin master to RTV casting mold. Prototype in 3-7 business days after CAD lock. MOQ 20 pcs/design. 21 CFR 177.2600 is extraction of the article, not an FDA-approved factory. Pectin: pectin gummy molds. Hub: gummy molds.
Grams still beat a pretty bear
Send target piece weight, gelatin bloom/formula notes if you have them, finished dimensions, logo, cavity count, tray size, fill method (hand, flood-and-scrape, or depositor pitch from a *drawing*), and market. A visual "looks like 4 grams" cavity is how outer-row pieces miss the pack weight.
Logo islands still need draft. Hairline serifs belong in print - logo molds.
Condensation and cold trays
A tray pulled from a cold room can wet the cavity face. Gelatin sticks to that film and tears a thin ear. Dry the face; don't raise Shore A to "fight moisture." Tin-cure is the wrong food start.
When this gelatin advice does not apply
Pectin SKUs belong on the pectin page. Vitamin/CBD grams-as-CTQ pages are separate. Steel high-volume tools → an HTV product RFQ here. A one-cavity kitchen dump can skip a production jacket. Geometry can override quantity: a negative-draft ear still needs a fillet at 80 dumps.
If you only have photos, custom 3D modeling is USD $50 when that scope applies.
Gelatin RFQ to copy
- Process: platinum RTV food-contact tray
- Target grams (e.g. 4.0 g); gelatin (not pectin)
- Fill method; depositor drawing if any
- Jacket / pan: yes/no
- Market; 177.2600 / LFGB
- Custom 3D modeling: USD $50 when that scope applies
- Prototype with real gelatin, then MOQ 20 pcs/design
- Acceptance: weigh every pocket; no stretch on agreed demold time
Send grams, gelatin notes, and tray size to contact ([email protected] / +86 135 3006 2969). Licheng Technology Industry Park, Xinhe Blvd, Shajing, Baoan.
Matched CTA: Send gelatin target grams and demold time for a jacket-and-Shore review - not a pectin spec pasted over, and not a generic free quote.
We would not recommend copying a pectin tray onto gelatin without a dump test
We would not recommend raising Shore A to hide a wet, cold cavity. We would not skip outer-row weights. We would not call 177.2600 a factory approval. We would not paste LIM math onto a gelatin slab.
RUUIPON Mold Structure Decision: open-back if draft peels. Loaded tray? mother mold. Early-demold stretch? wait or change wall - extra cavities don't set gelatin faster.
- CAD grams frozen? - no -> 1-2 cavity prototype
- CAD grams frozen? - yes -> Jacket keeps sheet flat?
- Jacket keeps sheet flat? - no -> Mother mold / board
- Jacket keeps sheet flat? - yes -> Weigh every pocket at agreed demold
- Weigh every pocket at agreed demold -> Pieces stretch or outer-row 3-6% off?
- Pieces stretch or outer-row 3-6% off? - yes -> Mother mold / board
- Pieces stretch or outer-row 3-6% off? - no -> Lock Shore and recast master

| Item | Typical shop value |
|---|---|
| MOQ | 20 pcs/design after sample approval |
| Custom 3D modeling | USD $50 when that scope applies |
| Prototype | 3-7 business days after CAD lock |
| Mix | Platinum 1:1 or 10:1; vacuum degas |
| Cavity Shore | 20A-30A production tray; confirm vs pectin |
| Platinum shrink | About 0.1-0.3% after full cure |
| Loaded-tray edge sag without a jacket | About 0.5-1.5 mm |
| Target piece | 4.0 g from volume x formula density |
| Outer-row vs center if tray sags | Edge often 3-6% heavy vs the center pocket |
FAQ
Is gelatin easier to demold than pectin? Often less sticky, yes. Early peel still distorts. Test your formula; don't assume.
Why did outer-row pieces weigh more? The sheet sagged. Add a jacket. Same physics as pectin.
Is this an FDA-approved factory? No. 21 CFR 177.2600 is extraction of the finished article.
Can I use the same tray for pectin later? Maybe, if Shore, jacket, and peel survive the stickier dump. Prototype; don't assume.
Do I need a prototype before MOQ 20? For a new gelatin shape, yes. 3-7 business days after CAD lock.
