How about the lead time?

Generally,1-2 weeks for samples, 3-4 weeks for mass production.

How do you control the quality?

(1)Material inspection--Check the material surface and roughly dimension. (2)Production first inspection--To ensure the critical dimension in mass production. (3)$ampling inspection--Check the quality before sending to the warehouse. (4)Pre-shipment inspection--100% inspected by QC assistants before shipment.

What will you do if we receive poor quality parts?

Please kindly send us the pictures, our engineers will find the solutions and remake them for you asap.
