FAQ：

Q：Do you accept small-batch customized orders (e.g., 50-100 units)? What is the delivery cycle?
A：We accept small-batch customized orders, with a minimum order quantity as low as 50 units. The delivery cycle for such orders is usually 1-2 weeks (depending on product complexity). During production, the "lean CELL production unit" is used to quickly switch production lines, ensuring efficient delivery of small-batch orders to meet your R&D prototyping and small-batch trial production needs.
