Current guidance on dimensional acceptance
Molded polymer behavior is not metal machining behavior. ISO 20457:2026 is the current international plastic molded part tolerance framework.
| Design feature | Review first |
|---|---|
| Wall thickness | Uniform cooling and avoid hidden heavy sections |
| Draft and ejection | Part release path, texture and witness marks |
| Dimensioning | Functional datums and realistic tolerance allocation |
| Conditioning | Time, humidity and measurement fixture |
| Approval | Sample quantity, acceptance owner and controlled revision |

MOQ depends on part type and order value. New customers may request 1–5 samples where suitable. Mixed models are possible at around USD 1,500 total. Small 1–2-piece orders can cost more per piece. Indicative lead times: standard items 10–25 working days; custom parts 20–45; project equipment 45–120. EXW, FOB, CIF and DAP are common; FCA, CFR, CPT, CIP and DDP can be agreed case by case.
