Custom RTV Ice and Garnish Molds for Hospitality Service
A mold that lives on a cocktail station or in a hotel pastry fridge is not a retail gift tray. Staff have to fill it, move it, freeze or cool it, demold it, and wash it without adding two minutes to a ticket.
This path is for bars, restaurants, hotels, beverage brands, and event programs that need branded ice, garnish, or chocolate tools in food-contact platinum RTV — at MOQ 20 after a prototype that a human can actually pop during service. RUUIPON, Shenzhen / Bao'an since 2018. If procurement wants food-contact paper, name the market first. If you need a molded silicone *part* (a silicone tumbler, lid, gripper) tooled in steel, that's an HTV product RFQ here.
Who this is for
Beverage directors, pastry leads, hotel procurement, and brand teams rolling a signature cube, spear, sphere, or garnish across one venue or several. Priorities: demold time, tray handling with wet gloves, freezer envelope, logo depth that reads in the glass, and documents a purchasing file will accept.
Not for: Amazon impulse ice trays, or silicone drinkware as a part program.
Typical job
A 50 mm logo cube, open-back tray, 6 cavities, must sit in a named under-bar freezer, bartenders demold by peel in a few seconds, FDA/LFGB-related papers for a US or EU property set, first buy 20 trays after a freeze test. Platinum food-contact RTV, draft on the logo so it doesn't hold the cube hostage, optional lid, jacket or frame if a large sheet dishes in the freezer.
Variant: a sphere or spear that needs an inner core or a two-part so the ice releases as a whole. That's a pull-path problem. If the core can't extract, you designed a cut mold, not a service mold.
Chocolate garnish and butter stamps for pastry follow the same service test: can the station hit piece count on a Friday night, and does the master finish show in the plate?
Common mix-up: approving the shape from a hero photograph. A beautiful sphere that takes two minutes and a tap with a spoon is the wrong hospitality tool.
What to send
- Ice or garnish size, target look (cube, sphere, spear, logo)
- Logo art and how deep it must read in a dark spirit
- How it is filled, frozen or cooled, demolded, and washed (including dishwasher or not)
- Freezer / rail envelope and whether a lid is required
- Piece count per shift and number of properties if this is a group roll-out
- Destination market and the procurement document list (21 CFR 177.2600 extraction and/or LFGB / BfR XV — not “FDA-approved factory”)
- Current failure: stuck logos, cracked spheres, floppy trays, slow demold
Typical shop values
Reference values only. Confirm material-specific limits against the supplier’s technical data and agree project acceptance criteria before production. Confirm against your freezer and staff test.
| Item | Typical shop value |
|---|---|
| Open cube / stamp tray | Open-back food-contact platinum RTV |
| Sphere / hollow / two-sided | Keyed split and/or inner core with a real pull path |
| Cavity Shore | Soft enough to peel fast; jacket if the tray is large and floppy |
| Mix | Platinum 1:1 or 10:1; vacuum degas until the foam collapses |
| Linear shrink | ~0.1–0.3% platinum, compensated on the master |
| Logo | Depth + draft so it reads in the glass and still releases |
| Docs | Compound + market: 21 CFR 177.2600 and/or LFGB / BfR XV |
| MOQ / prototype | 20 mold pieces per design; freeze/demold test after CAD lock (often 3–7 days) |
| Multi-site | Freeze the CAD and master; recast additional trays to the same reference |
When RUUIPON is the wrong quote
We would not quote this path if:
- You need molded silicone parts (tumblers, lids, ice buckets as goods) → an HTV product or mold RFQ here, or ask us if you need a high-volume LSR cold-runner tool HCR / LSR steel.
- You need a catalog impulse tray and will never test it on the rail.
- The “ice mold” is actually a commercial ice machine evaporator part. Different industry.
A 20-tray logo-cube pilot for one bar group belongs here. A 5,000-unit silicone tumbler launch does not.
RUUIPON Mold Structure Decision
- Flat-back cube / stamp? - sphere / spear / two-sided -> Can staff peel it in seconds?
- Can staff peel it in seconds? - yes -> Open-back RTV
- Can staff peel it in seconds? - no -> Keyed split / inner core — design the pull path
- Procurement docs? - EU -> LFGB / BfR XV
We would not recommend…
We would not recommend a decorative retail mold that looks right in a photo and dies on a Saturday rail. We would not skip the core pull-path on a sphere. We would not freeze a multi-property PO from CAD alone — run the freeze and the wash. We would not treat 21 CFR 177.2600 as an FDA factory stamp. We would not ask us steel parts on this form just because the brand also wants tumblers.
What to ask when you're buying
- What's the demold method, and have you timed it with wet gloves?
- Does the tray fit the freezer we named, with or without a lid?
- Open-back, split, or core — and who owns the master for recasts at the next property?
- Which food-contact documents ship for this compound and market?
- Can additional sites reorder the same cavity without redrawing?
Worked example: 50 mm logo cube, 6-up, under-bar drawer 60 mm clear height, 20 trays, US hotels. Open-back platinum food tray, logo draft, no core, docs = 21 CFR 177.2600 path on the article. A 55 mm sphere for the same program is a second tool: two-part or core, not a stretched cube tray.
Matched next step
Send ice size, logo art, freezer envelope, and how staff will fill, demold, and wash. We'll name structure, docs, and whether this stays RTV or is a finished part.

FAQ
Why not just buy a retail logo tray? Retail trays aren't sized to your freezer, your logo depth, or your wash. Custom RTV is for service: envelope, peel time, and a master you can recast when property four comes online.
Do spheres need a different mold than cubes? Usually. Cubes are often open-back. Spheres and spears need a split or a core with a pull path. Don't assume one tray does both.
What food-safety paper can procurement get? Papers that match the compound and market — 21 CFR 177.2600 extraction and/or LFGB / BfR XV. Ask for that list up front. There is no honest “FDA-approved factory” badge.
Can several hotels use the same tool record? Yes, if we keep CAD, master, compound, and sample together. That's how cavity five matches cavity one six months later.
When do I are an HTV product RFQ here, or a different LSR-tool RFQ - ask us? When the buy is a molded silicone *part* (drinkware, lids, molded goods) and steel HCR/LSR tooling, not a cavity you freeze water in. We'll say so on the RFQ.
