During Production Check (DUPRO)
When production reaches 50% and packaging begins, our inspectors will randomly select samples from semi-finished and partially packaged finished products for inspection and testing. This helps identify early problems to prevent continued production of large quantities of defective products. They will also recommend effective improvement measures and provide timely feedback to customers. During this phase, we identify problems early and propose improvement plans, helping us predict the factory's production efficiency and completion time.
