Q1: What is your production lead time?

A: Prototype samples can be delivered in 2-3 days. Formal pre-production samples take 1-2 weeks. Mass production lead time is typically 3-4 weeks, depending on order quantity and complexity. Rush orders for optical imaging projects can be accommodated upon request.

Q2: How to get accurate quotation?

A: Please send us your 3D drawings (STEP/STP/IGS/XT), 2D drawings (PDF/DXF/DWG), or physical samples. Include material specifications, surface treatment requirements, and target quantity. Our engineering team will review and provide a detailed quotation within 24 hours.

Q3: Can I quote without technical drawings?

A: Yes, we can provide a rough estimate based on product photos, dimensions, and description. However, for precise pricing and manufacturability analysis, technical drawings or physical samples are strongly recommended, especially for complex optical instrument housings.

Q4: Will you leak my design drawings?

A: Absolutely not. We strictly protect all client intellectual property. We are happy to sign NDA (Non-Disclosure Agreement) before receiving any drawings. Your optical instrument housing designs, prototypes, and production data remain fully confidential.

Q5: Can you provide pre-production samples?

A: Yes, we strongly recommend pre-production samples for first-time orders. This allows you to verify fit, finish, and function before committing to mass production. Sample costs are typically refunded or deducted from bulk order totals.

Q6: How do you handle defective products after delivery?

A: We maintain a strict quality control system with 100% inspection before shipment. In the rare event of defects, please contact us within 7 days of receipt. We will analyze the issue, provide replacement parts or full refund, and implement corrective actions to prevent recurrence.
