Часто задаваемые вопросы
- What’s the most important factor when choosing a supplier for a thin-walled aluminum prototype (0.8ММ толщина)?
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. Также, verify they use precision CNC machines (с точностью ± 0,01 мм) 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 (НАПРИМЕР., anodization tanks, electroplating lines) and ask how long surface treatment typically adds to the delivery time—outsourced services often add 5+ дни.
- If I need both a prototype and future mass production, should I choose the same supplier?
Да, if the supplier has scalability. Confirm they have mass production equipment (НАПРИМЕР., 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.
