Etsy Restock Cavity Count: How Many Cavities Before You Add a Second Tray
Etsy restocks stall when one 6-cavity tray cannot hit weekend orders. How RUUIPON sizes cavity count vs a second tool at MOQ 20.

Friday: 18 orders. Your 6-cavity tray needs three full pours and overnight cure. You miss the handling window. Adding cavities is not free - the sheet gets heavier and the center cavities cure different if you ignore spacing.
RUUIPON sizes restock trays for makers who already sell, MOQ 20 of that layout. Not a mogul-line conversation. Layout depth: multi-cavity layout.
The Weekend Order Spike
Write pieces per weekend, not "I want as many cavities as possible." We can put 24 tiny studs on a sheet that you cannot demold without tearing. Labor wins.
Cavities vs Demold Minutes
| Weekend pieces | Starting talk |
|---|---|
| Under ~30 | 6-8 cavities often enough |
| ~30-80 | 12-16 or a second 8-cavity |
| 100+ | Two tools or a larger sheet after a prototype pour |
These are talk bands from shop RFQs, not a capacity cert. Your cure time changes the math.
Second Tray vs More Cavities
A second identical 8-cavity is often cheaper in labor than a floppy 24-cavity. MOQ is 20 per design - two identical layouts are still one design if the CAD is the same. A different OD is a second design.
Layout Notes We Will Argue
Spacing, edge distance, and sheet thickness. We push back on cavities stacked so tight you cannot get a finger under the pour. Quote ~24h. Prototype 3-7 days after CAD lock.
FAQ
Does more cavities lower piece price of the mold?
The tray price is for the tool, not per cavity royalty. More cavities can raise the tray price if the sheet grows.
Can I mix SKUs on one restock sheet?
Yes. Demold and Shore become a compromise. See jewelry vs coaster notes.
