Silicone molds for vitamin gummies: grams as CTQ, not a dosing claim
A vitamin gummy mold is still a platinum RTV cavity. Your label may care about milligrams of a nutrient; we care about cavity volume, formula density, and whether a loaded tray sags so outer-row 4 g pieces run 3-6% heavy. We don't make dosing, potency, or supplement claims. If pack weight is a CTQ, we size the pocket from grams and density, then jacket the sheet. RUUIPON pours these tools 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. Name pectin vs gelatin - most vitamin SKUs behave like pectin or gelatin. Hub: gummy molds. CBD tooling (no dosing claims): CBD gummy molds.
Weight map before artwork
Send target piece weight, formula family, finished dimensions, logo, cavity count, fill method, and market. Approving a generic "food grade" badge without matching the report to the compound is a procurement fail - food-grade. A tray that twists when every cavity is filled is a jacket fail, not a Shore mystery.
Fine logo detail traps sticky product. Draft the mark - logo molds.

US / EU / both on the RFQ. A late discovery that you need different US vs EU files is how you recast. Color is part of the article.
When this vitamin-tray advice does not apply
We don't design nutrient delivery or claim a gummy treats anything. Steel high-volume *part* tools → an HTV product RFQ here. A kitchen one-off can skip multi-cavity. Geometry can override quantity: a locked mascot still needs draft at 80 dumps.
If you only have photos, custom 3D modeling is USD $50 when that scope applies.
Vitamin-gummy RFQ to copy
- Process: platinum RTV food-contact tray - tooling only
- Target grams; pectin vs gelatin
- No dosing/potency fields for the mold shop
- Cavity count; tray size; fill method
- Jacket yes/no
- Market; 177.2600 / LFGB on this compound
- Custom 3D modeling: USD $50 when that scope applies
- Prototype weigh-map, then MOQ 20 pcs/design
Send grams, formula family, and tray envelope to contact ([email protected] / +86 135 3006 2969). Licheng Technology Industry Park, Xinhe Blvd, Shajing, Baoan.
Matched CTA: Send target grams and pectin vs gelatin for a weigh-map review - we will not quote a dose, and this is not a generic free quote.
We would not recommend treating cavity milliliters as a nutrient dose
We would not recommend a generic food-grade PDF that doesn't name this compound. We would not skip outer-row weights on a 4 g SKU. We would not call 177.2600 a factory approval. We would not make medical or supplement claims for the mold.
RUUIPON Mold Structure Decision: grams first, then dump family. Open-back if draft peels. Loaded tray? jacket. Steel or LSR part tools? Ask us.
- Target grams named? - no -> Don't guess from a mascot photo
- Target grams named? - yes -> Pectin or gelatin?
- Pectin or gelatin? -> Jacket keeps sheet flat?
- Jacket keeps sheet flat? - no -> Nest / board
- Jacket keeps sheet flat? - yes -> Weigh every pocket
- Nest / board -> Weigh every pocket
- Vitamin gummy tray -> Need steel parts?
- Need steel parts? - yes -> HTV product or mold RFQ

FAQ
Will this mold guarantee each gummy contains the labeled nutrient? No. We tool a cavity to agreed grams. Dosing is your formula and process, not the mold shop.
Is RUUIPON an FDA-approved factory? No. 21 CFR 177.2600 is extraction of the finished rubber article.
Do I still need pectin vs gelatin on the RFQ? Yes. Stick and peel change Shore and jacket even when grams are identical.
Can I start from a PNG of the mascot? For a first look. For volume, send STEP/STL. Custom 3D modeling is USD $50 when that scope applies.
When do I need a prototype? For a new 4 g SKU, yes. 3-7 business days after CAD lock. Weigh every pocket.
