Custom Silicone Molds for Marshmallows: Stick, Draft, and Dose

Marshmallow slurry sticks harder than chocolate and foams as it sets. A tray that demolds candy can tear foam skins or leave sugar film in corners. RUUIPON builds food-grade confectionery silicone molds at MOQ 50 with prototypes in 3-7 days when stick and dose are locked on sample.

Quick answer: Shore A 30-45, 1-3 deg draft, edge radius on lips, walls 2.5-5 mm, spacing 8-20 mm, platinum food-grade docs, and approve demold on your real slurry - not water.

Sticky Release

Sugar films and gelatin skins cling to sharp corners. Soft Shore helps peel, but too soft collapses tall shapes. Balance Shore with draft and radius - edge radius and tear strength. Food-safe release only when your process allows - release guide.

Dose and Shape

Piece weight drives claim and packing. Measure cavity volume, then adjust for foam expansion - cavity volume. Logo and text depth follow the same limits as other soft candies - text legibility.

Food-Grade Path

Treat as food contact: FDA vs LFGB and docs checklist. Odor transfer matters on sweet foam - odor and taste.

Tray Layout

Tall marshmallows need spacing for wall strength - start 8-20 mm - layout guide. Dense trays cool unevenly and stick more.

Frequently Asked Questions

Sometimes, but stick and foam differ - prototype first.

Two-part molds?
Only if shape undercuts lock - two-part vs one-part.

MOQ / lead time?
