When receiving customer’s affirmation, we will carry out production within 60 days. During production, we will implement final test to service pieces of samples in advance and send them to the customer for affirmation. We can not execute mass production until we receive the affirmation from customer.
During the course of production, LONGFAVOR quality control department will control product quality on site. In addition, it is greatly welcomed if customer appoints QC to site instruction.
