The tart looks sharp until the last 2 mm of the cavity holds the wax and you rip the logo off the face. Soy shrink and fragrance load change stick. We quote tart cavities as wax work, not chocolate.
RUUIPON cuts custom silicone molds in Shenzhen since 2018 for brand and Shopify buyers, not kitchen DIY kits. MOQ 20 trays per design. Complete RFQs typically get a reply in about 24 hours. Prototype is commonly 3-7 business days after CAD lock. Drawing deposit ~$50 USD when we must model cavities.
The Last 2 mm Is Where Tarts Stick
This section is the failure mode we see on restock, not a keyword definition. If the first sample looked fine, wait until cavity 8-20 before you approve a production sheet.
Fragrance Load vs Stick, Not vs Brand Story
| Input | What it does to the tray |
|---|---|
| Zero draft tart | Sticks at the rim |
| Draft 1-3 deg | Usual wax start |
| Logo 0.25 mm | Fills with fragrance oil bloom |
| Same cavity as chocolate | Wrong Shore and temp story |
Candle/wax product path exists. This URL is tarts as a restock SKU for brands, not pillar candles.
Melt Temp on the RFQ
Do not reuse a Shore band from a different fill. Platinum-cure is the default production sheet. Shrink is compensated in CAD (~0.1%) when you send a solid. We do not lock a marketing cycle-life number.
Tart RFQ
Cavity grams target, melt C, fragrance % if known, logo depth.
Candle molds: candle molds. Wax seal kits are a different tool: wax seal kits.
