custom silicone gummy molds
Custom silicone gummy molds that survive sticky demold
When sticky pectin stretches soft trays and piece weight drifts, you need custom silicone gummy molds cut for your grams, Shore A, and FDA/LFGB path - MOQ 20, prototype in 3-7 days.

Problems sticky gummy formulas create for molds
If you deposit pectin or gelatin into a soft tray that stretches on demold, piece weight drifts 5-8% on outer cavities, logos smear, and operators fight every cycle. Catalog trays solve none of that - they were not cut for your target grams or your depositor footprint.
Buyers searching custom silicone gummy molds usually need three outcomes at once: a branded cavity that retail recognizes, food-grade docs for US/EU buyers, and a path that does not force MOQ 200-3000 finished goods before the SKU proves out.
- Sticky demold stretch - soft walls enlarge cavities after peel; weight variance climbs
- Tray oil-canning - large soft sheets twist under depositors; fill height uneven
- Missing FDA/LFGB paper - retailers reject undocumented silicone
- Steel CapEx too early - logo changes strand a metal tool before sell-through is proven
RUUIPON builds the cavity tools you cast with - platinum-cure, Shore A matched to your formula, multi-cavity only when the tray will stay flat. You keep control of the recipe; we make the mold behave.
What you get with a RUUIPON gummy mold
You are not buying a finished gummy OEM run. You get production silicone tooling so you (or your co-packer) can deposit, demold, and pack branded pieces.
| Decision | What you lock in |
|---|---|
| MOQ | 20 mold pieces per design - test SKUs without a 300-1000 finished-goods trap |
| Prototype | 3-7 business days after CAD approval - cast your real pectin/gelatin before production |
| Quote | Typically within 24 hours on complete files (shape, target grams, market) |
| Shore A | 25A-35A for sticky demold; raise toward 35A-45A when tray span must stay flat |
| Food path | Platinum-cure food-grade with FDA / LFGB docs on request |
| Layout | 6-24+ cavities when spacing and walls allow - or we split trays instead of cramming |

Shore A and food-grade silicone for gummies
Wrong hardness costs more scrap than a slightly firmer tool. Sticky pectin wants flex to peel; a floppy 24-cavity sheet wants mid Shore so the pour surface stays level.
| Use | Typical Shore A | Why it helps you |
|---|---|---|
| Detailed logo / deep undercut pieces | 25A-30A | You demold without tearing thin arms or logo edges |
| Standard multi-cavity pectin trays | 30A-35A | Balance sticky peel vs wall stretch |
| Large flat depositor trays | 35A-45A | You keep fill height consistent across the sheet |
Platinum-cure is our production default (~0.1% shrink compensated on the master). Tin-cure hobby compounds are a short-life trap for food programs. Docs path: FDA vs LFGB. Hardness deep dive: Shore A guide.
DFM that keeps piece weight stable
Before we cut a master, we review your file the way a depositing line will punish it.
- Draft 1-3° on vertical walls when geometry allows - soft silicone forgives mild undercuts; draft still extends life on every cavity
- Target grams stated up front (e.g. 2.5 g / 5 g) with an acceptable variance band - not "exact" with no tolerance
- Cavity spacing often 3-6 mm+ between small pieces so walls do not tear
- Wall thickness biased up when sticky demold would stretch outer cavities
- Logo depth typically 0.3-0.8 mm - knife-edge text looks sharp in CAD and fails in production
Multi-cavity count is a production decision, not a brochure boast. If a 24-up sheet will warp at the Shore your recipe needs, we recommend two 12-up trays at MOQ 20 each. Layout notes: multi-cavity silicone mold design.
Files: STEP / STL / IGES / PDF / photos / physical sample. Incomplete RFQs stall on cavity debates a sketch could settle in five minutes.
From file to deposited trays
- Quote - shape, target weight, cavity range, US/EU docs need
- DFM - Shore A band, draft, split-tray call, food-grade path
- Master - shrink compensation ~0.1% across cavities
- Prototype - 3-7 business days after CAD approval; you test with your formula
- Production - vacuum-degassed platinum tooling, cavity QC, test cast, pack
- Reorder / revise - same tooling for repeats; geometry or Shore change is a revision line item
When daily volume outgrows RTV economics, we say so - soft tooling is not fake steel. Cost framing: silicone mold vs steel mold cost. Why start at 50: MOQ 20 vs 300.
Custom silicone vs catalog vs steel
US catalog shops often sell fixed packages (prototype deposits, 20-mold / 100-mold kits). China finished-goods OEMs often quote MOQ 200-3000 molded products. RUUIPON sits in the mold-tooling lane for brands that cast.
| Path | You get | Best when |
|---|---|---|
| Marketplace catalog tray | Shared shapes, thin docs | Hobby tests only |
| RUUIPON custom silicone | Your cavity, MOQ 20, FDA/LFGB path, 3-7 day prototype | Brand launch, nutraceutical, seasonal SKUs |
| Steel production mold | High cycle life, high CapEx | Locked geometry, high daily pours |
Sister brand WYD handles steel confectionery programs when volume justifies it. We will not pretend a soft tray matches steel cycle life - and we will not push steel into a 50-piece launch.
QC and documents you can hand to retail
- Master checked against approved CAD
- Prototype approval before production quantity
- Cavity visual + dimensional spot checks; tray flatness on multi-cavity tools
- FDA / LFGB material reports on request for food-contact grades
- Batch CoC available when your QA file needs it
Finished gummy compliance (recipe, label, allergen) stays on your side. Tell us the market at quote so compound and paperwork match.
FAQ for gummy mold buyers
Are molds food-safe?
Food-contact projects use platinum-cure food-grade silicone. FDA and/or LFGB docs on request.
Is MOQ 20 cavities or 20 trays?
20 mold pieces per design. A 16-cavity tray still counts as one piece in the run.
Can you match a competitor gummy?
Only with rights you own. Send original art or a sample you are authorized to tool.
Will trays run on a depositor?
Yes when Shore A and flatness match the line. Send tray footprint and nozzle notes with the RFQ.
How fast is a quote?
Complete files usually within 24 hours.
How do I start?
Send shape, target grams, and market - we reply with Shore A, cavity layout, and lead time.
