- Better Quality Control: The supplier oversees the entire process, ensuring machining and surface treatment align (PER ESEMPIO., 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, & Scalabilità della produzione
Your project’s timeline and volume needs (prototyping vs. produzione di massa) should align with the supplier’s capabilities.
3.1 Tempi di consegna & MOQ Comparison for Different Project Stages
| Project Stage | Ideal Supplier MOQ | Target Delivery Time | Key Supplier Question |
| Initial Prototype (1-5 pezzi) | 1 piece (low MOQ) | 3-7 Giorni di lavoro | “Can you meet a 5-day turnaround for a single aluminum prototype with anodization?" |
| Iterazione di progettazione (5-20 pezzi) | ≤5 pieces | 7-10 Giorni di lavoro | “If I modify the design slightly, how much will the delivery time change?" |
| Pre-Mass Production (20-100 pezzi) | ≤20 pieces | 10-15 Giorni di lavoro | “Do you have enough capacity to scale from 20 A 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, macchine per stampaggio a iniezione, or high-volume CNC lines (not just prototype-focused machines)?
- Supply Chain Stability: Can they source materials consistently for large orders (PER ESEMPIO., bulk aluminum or stainless steel)?
- Certificazioni di qualità: Do they have ISO 9001 (Gestione della qualità) or IATF 16949 (ricambi auto) certifications—critical for mass production compliance?

Yigu Technology’s Viewpoint
Choosing a hardware prototype supplier is about balancing capacità, affidabilità, and alignment with your project goals. Yigu Technology recommends prioritizing suppliers with in-house machining and surface treatment—this cuts down on delays and ensures quality control. For precision-focused projects (PER ESEMPIO., medical or electronic prototypes), Suzhou or Shenzhen suppliers are ideal due to their advanced equipment and expertise. Always test a sample first: a single prototype reveals more about a supplier’s attention to detail than any certification. Inoltre, think long-term—if you plan to scale, select a supplier with mass production capacity to avoid switching partners later. Finalmente, clear communication of your requirements (tolleranze, Trattamento superficiale, delivery time) from the start is key to a successful partnership.
Domande frequenti
- What’s the most important factor when choosing a supplier for a thin-walled aluminum prototype (0.8spessore mm)?
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. Anche, verify they use precision CNC machines (con precisione di ± 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 (PER ESEMPIO., anodization tanks, electroplating lines) and ask how long surface treatment typically adds to the delivery time—outsourced services often add 5+ giorni.
- If I need both a prototype and future mass production, should I choose the same supplier?
SÌ, if the supplier has scalability. Confirm they have mass production equipment (PER ESEMPIO., 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.
