Minimum order quantity (MOQ) for CNC and injection molding in China is process-dependent, not a single factory rule. CNC prototypes often start at one piece; molding MOQ follows tool design, resin packaging and setup economics.
Minimum order quantity (MOQ) for CNC and injection molding in China is process-dependent, not a single factory rule. CNC prototypes often start at one piece; molding MOQ follows tool design, resin packaging and setup economics.
Planning MOQ early avoids overbuying resin or under-specifying cavities for your real annual volume.
CNC and prototype MOQ
Machined metal or plastic prototypes typically allow MOQ 1 piece because there is no soft tool amortization. Price per piece falls when fixtures and programs are reused across a small batch (10–50 pcs). Rapid prototypes via SLA/SLS/MJF have their own batch economics but also support low quantities.
Injection molding MOQ drivers
- Cavity count and cold vs hot runner waste.
- Resin bag size and color masterbatch minimums.
- Machine setup and color change time.
- Packaging and export carton efficiency.
| Proces | Typical MOQ band | Notes |
|---|---|---|
| CNC prototype | 1+ pcs | Setup dominates cost |
| CNC small batch | 10–200 pcs | Fixture reuse helps |
| Pilot molding | ~100–1,000 pcs | Depends on tool & resin |
| Production molding | program-specific | Align to annual volume |
| Odlití | often higher than CNC | Tool + shot economics |
How to negotiate MOQ without quality risk
Share your 12-month forecast and first PO size. Factories can propose single-cavity tools for validation, then multi-cavity for scale. Avoid forcing ultra-low MOQ on multi-cavity hot-runner tools if resin waste and setup make it uneconomic—consider CNC bridge production instead.
Bridge manufacturing options
- CNC or vacuum casting while steel mold is cutting.
- Aluminum soft tools for mid hundreds of shots.
- Same-factory handoff so datums and DFM carry forward.
HC-Mold commercial practice
Prototype CNC often starts at MOQ 1 piece. Molding MOQ is quoted per program after resin and tool design are known. Free DFM, reply ≤12h, quote ≤24h on complete RFQs. ISO 9001:2015 in Chang'an, Dongguan.
Forecast accuracy and MOQ conversations
Factories size resin purchases, cavity steel and packaging around your forecast. A stated “500 pcs MOQ” may simply reflect one efficient run plus purge waste for a two-cavity cold runner—not a hard corporate rule. Share optimistic and conservative annual volumes so engineering can propose a single-cavity pilot tool versus jumping to eight cavities.
Color and material changes reset effective MOQ because barrels must be purged. Consolidate SKUs where branding allows. For CNC, batching revisions under one setup window lowers unit cost even when each revision is formally MOQ 1.
Document MOQ in the purchase order alongside price breaks. Ambiguous email threads create disputes when marketing later requests 80 pcs of a molded color that only runs efficiently at 800. HC-Mold will state program-specific MOQ after reviewing drawings and resin notes.
Buyer checklist before you issue the PO
Confirm drawings are revision-controlled, materials are purchasable in China within your schedule, and inspection methods are agreed in writing. Ambiguity at PO stage becomes cost later. List secondary operations, packaging and labeling so they are not treated as free extras. If multiple factories are bidding, freeze the same specification package for all—do not let informal calls create hidden scope differences.
Align internal stakeholders: industrial design owns cosmetics, engineering owns function, procurement owns total cost and risk. A single RFQ owner should consolidate feedback so the manufacturer receives one voice. For export programs, involve logistics early on Incoterms preference and whether tools or finished goods will cross borders.

FAQ
Is 500 pcs a universal molding MOQ?
No. Some pilot tools support lower; others need higher to clear setup and resin. Always state your true need and ask for options.
Can MOQ differ by color?
Yes. Color changes add purge waste. Combine colors in one campaign when possible.
Does multi-cavity force higher MOQ?
Often yes for efficient runs, but you can still order partial if you accept higher unit cost.
