For high-precision turned components, Reban typically achieves a concentricity of ±0.01mm. Our advanced CNC turning centers and specialized work-holding fixtures allow us to maintain tight geometric tolerances. If your design requires even higher precision, our engineering team will review your drawings to provide a customized manufacturing strategy.
5.What is your sampling policy and associated charges?
At Reban, we understand the importance of physical validation before mass production.
- Sampling Fee: For clients who require a prototype prior to a batch order, we charge a sampling fee (typically 3–5 times the mass production unit price) to cover the specialized setup and machine time.
- Refund Policy: Once the subsequent batch order is confirmed, the sampling fee difference is fully credited or refunded to the customer, effectively making the prototype a part of the production investment.
6.How does Reban handle quality discrepancies?
Your satisfaction is our priority. If you receive parts that do not meet the agreed-upon specifications:
- Resolution: Simply provide us with measurement data or photographic evidence of the discrepancy.
- Guarantee: Reban will repair or remake the parts for free and cover all additional freight costs to ensure your project stays on track without extra expense.
