| Gravure laser (Logos, Part Numbers) | Add identification or branding (prototype labeling for testing) | “What’s the minimum font size you can engrave? Does engraving affect the part’s structural integrity?» |
2.2 Benefits of One-Stop Service
- Faster Turnaround: No time lost shipping parts to third-party surface treatment providers (reduces delivery time by 30-50% en moyenne).
- Better Quality Control: The supplier oversees the entire process, ensuring machining and surface treatment align (Par exemple, no scratches from handling between processes).
- Simplified Communication: One point of contact for both machining and surface treatment, reducing miscommunication about requirements.
3. Review Delivery Time, MOQ, & Évolutivité de la production
Your project’s timeline and volume needs (prototypage vs. production de masse) should align with the supplier’s capabilities.
3.1 Délai de livraison & MOQ Comparison for Different Project Stages
| Project Stage | Ideal Supplier MOQ | Target Delivery Time | Key Supplier Question |
| Initial Prototype (1-5 pièces) | 1 morceau (low MOQ) | 3-7 jours ouvrables | “Can you meet a 5-day turnaround for a single aluminum prototype with anodization?» |
| Itération de conception (5-20 pièces) | ≤5 pieces | 7-10 jours ouvrables | “If I modify the design slightly, how much will the delivery time change?» |
| Pre-Mass Production (20-100 pièces) | ≤20 pieces | 10-15 jours ouvrables | “Do you have enough capacity to scale from 20 à 100 pieces without delaying delivery?» |
3.2 Scalability for Future Mass Production
If you plan to move to mass production after prototyping, evaluate the supplier’s long-term capacity:
- Production Equipment: Do they have stamping presses, Machines de moulage par injection, or high-volume CNC lines (not just prototype-focused machines)?
- Supply Chain Stability: Can they source materials consistently for large orders (Par exemple, bulk aluminum or stainless steel)?
- Certifications de qualité: Do they have ISO 9001 (gestion de la qualité) or IATF 16949 (pièces automobiles) certifications—critical for mass production compliance?

FAQ
- What’s the most important factor when choosing a supplier for a thin-walled aluminum prototype (0.8mm d'épaisseur)?
The supplier’s experience with low-vibration machining and specialized clamping tools is critical. Ask to see past examples of thin-walled parts—this ensures they can prevent deformation. Aussi, verify they use precision CNC machines (avec une précision de ± 0,01 mm) to maintain wall thickness consistency.
- How can I avoid delays from surface treatment outsourcing?
Choose a supplier that lists surface treatment as an in-house service (check their website or ask for a facility tour). Request proof of in-house equipment (Par exemple, anodization tanks, electroplating lines) and ask how long surface treatment typically adds to the delivery time—outsourced services often add 5+ jours.
- If I need both a prototype and future mass production, should I choose the same supplier?
Oui, if the supplier has scalability. Confirm they have mass production equipment (Par exemple, stamping presses for metal parts) and can handle larger MOQs. Using the same supplier reduces design transfer risks—they already understand your prototype’s requirements, making the shift to mass production smoother.
