Once the order placed, before mass production, we will make a pre-production sample to confirm with client. Take photos with different angles, show the details to our client, fix the not perfect parts. Once client confirms the sample, we will strictly produce according to it. There will be a production timeline and requirements made and notice each department manager in order to catch the delivery time and avoid any mistake. Moreover, a production track will be posted to client during production. Once the production finished, QC department will check the quality. Meanwhile, take photos again to confirm with client. If client will need the third part QC comes, we will arrange the time and cooperate with him.
