Your launch date assumes "molds in two weeks" - then CAD revision, sample fail, and CNY add six more. RUUIPON ships custom silicone molds at MOQ 50 with prototypes in 3-7 days after approved files - not after first email. This guide builds realistic buffers so your PO timeline matches factory floor reality.
Quick answer: Budget 3-7 days prototype after final CAD, +5-10 days for one revision cycle, +14-21 days production pour and post-cure at MOQ 50, +5-12 days freight. Total first order: plan 5-7 weeks door-to-door; reorder with frozen CAD: 3-4 weeks. Add holiday buffers for Chinese New Year (2-3 weeks) and Golden Week.
Lead Time Buffers Summary
| Phase | RUUIPON typical | Buffer to add |
|---|---|---|
| Quote + DFM | 1-3 business days | +2 days if complex multi-cavity |
| Prototype mold | 3-7 days | +3 days master build if RUUIPON CNC |
| Sample test (buyer) | 3-7 days | Your resin/chocolate cure time |
| Revision (if needed) | 5-10 days | One cycle in plan minimum |
| Production MOQ 50 | 14-21 days | +5 days peak season |
| Freight | 5-12 days express | +7 days sea if cost-saving |
Order Timeline Phases Explained
Lead time clocks start at different triggers - misalignment here causes most buyer frustration.
- Quote phase - starts when STEP/STL + application note arrive. Compare quotes.
- Prototype phase - starts at CAD sign-off, not PO deposit alone.
- Production phase - starts at written sample approval, not verbal "looks good."
- Ship phase - starts at QC pack-out. Packing & export.

Prototype 3-7 Day Buffer
Three days: simple one-cavity, buyer-supplied sealed SLA master, Shore A standard. Seven days: multi-cavity layout, two-part mold, CNC master from STEP, colored silicone.
| Prototype type | Days | What extends it |
|---|---|---|
| Single cavity, supplied master | 3-4 | Unsealed FDM master |
| 6-cavity tray, RUUIPON master | 5-7 | Undercut split design |
| Two-part with keys | 6-8 | Flash tuning iteration |
| Food-grade post-cure batch test | +2-3 | Odor/taste qualification |
Revision & Sample Test Buffers
Plan one revision cycle on first SKU - logo depth, draft, or spacing changes after first cast.
| Revision scope | Turnaround | Cost impact |
|---|---|---|
| Logo depth ±0.2 mm | 5-7 days | New master section |
| Cavity spacing widen | 7-10 days | Full re-layout |
| Shore A change | 5-7 days | Re-pour only if same master |
| Two-part split move | 8-12 days | New mold half |
Process: revision process. Approval checklist: sample approval checklist.
Production & Shipping Buffers
MOQ 50 production pour is not instant - vacuum degassing, cure, demold, trim flash, post-cure for food grades.
- Pour schedule - large trays batch 2-4 per day per line.
- Cure - platinum silicone 24-48 h before demold; post-cure 4-8 h @ 80-100 °C for food.
- QC - cavity caliper, Shore A spot check, flash trim. Flash QC.
- Ship - DHL/FedEx 5-8 days US/EU; sea 25-35 days.
Import customs buffer: importing from China.
Buyer-Side Delays That Blow Timelines
| Delay | Typical cost | Prevention |
|---|---|---|
| CAD units wrong (inch vs mm) | 3-5 days re-quote | Label STEP in mm |
| Artwork not vector | 2-4 days redraw | Artwork prep |
| Sample approval waiting 14+ days | Production queue slip | Test within 5 business days |
| Change cavity count at approval | Full re-layout | Lock layout at quote |

Frequently Asked Questions
Can prototype ship in 48 hours?
Only pre-approved repeat SKU with existing master - not new geometry.
Does paying rush fee skip the queue?
Rush available on case basis - adds 30-50% for 2-day prototype slot.
CNY shutdown?
Plan no production late Jan-mid Feb; add 3-week buffer on orders crossing that window.
MOQ 50 production days?
Typically 14-21 calendar days after sample approval.
Parallel prototype + production?
No - production starts after approved sample on new designs.
Amazon FBA deadline?
See Amazon FBA mold timing - add 2-week inbound buffer.
Vacuum degassing add time?
Built into standard pour - not extra days. Degassing.
