Orange Silicone Mold

Professional-Grade Orange Silicone Mold for Commercial Use

Eight cavities on one tray in a 4 × 2 layout, each moulding a citrus ball with its calyx star formed in place rather than cut in afterwards. Platinum-cured, food-grade silicone rated -40°C to 230°C, so one tray moves between oven, microwave, blast freezer and top-rack dishwasher without the star rounding out or the sphere walls going slack. The cavities sit in a flat frame with four corner locating holes, which lets the tray drop onto a standard sheet pan or wire rack and stay put instead of sliding when it is carried to the oven full. Shipped factory-direct from our own manufacturing site in China, sample to bulk in one workflow.

The tray photographs two ways, and the difference is worth understanding before you specify a tool. From the mould side you see eight round openings with a flat sealing rim; turn it over and the same eight cavities read as bulging spheres with the calyx star moulded into each crown. That star sits at the bottom of the cavity, which is why it comes out on the top of every finished piece — and why it is the detail to check on a sample. A shallow star on a cheap tool looks perfectly sharp in the mould and vanishes on the baked bun, because the dough rises past it and carries the impression away. The cavity depth is what makes the shape survive: it holds the full height of the dough as it proves and rises, so filled buns — custard, red bean, cream cheese — keep their crown instead of splitting at the rim.

The calyx is the detail that punishes sloppy handling. Overfill a cavity and the mix floods the crown and blunts it; an under-kneaded dough traps air against the mould and leaves the star pitted; and a bun turned out while the tray is still hot tears along the rim, because that is the thinnest part of the wall. Let the tray cool until it is comfortable to hold, flex it from the underside, and lift each piece out by its base. Warm water and a soft brush only — no blade and no scouring pad — and store the trays stacked rather than folded, so the sphere walls keep their shape for the next run.

Custom Silicone Mold Tooling

Silicone tooling is where our own mold shop matters: the cavity, the parting line and the draft angle decide whether a mold releases cleanly for two thousand cycles or two hundred.

• Cavity Design - send a sketch or a 3D file; we return a mold proposal with wall thickness and parting line marked.
• Cure and Hardness - platinum-cured as standard, with Shore A selected for the release behavior you need rather than the cheapest compound.
• Color - Pantone-matched compound, held on file so reorders do not drift.
• Logo - embossed in the steel so the mark is molded into the part and never washes off.
• Mold Fee - credited back against your first bulk production run.
