Analysis of Key Points for Raw Material Quality Control and On-Site Quality Control

Although we have discussed these two positions in detail before, what I would like to ask everyone now is how to enable the personnel in these two positions to give full play to their abilities and keep a good grip on both raw material quality and finished product quality. Could you repeat once more the details that the two positions need to pay attention to in their daily work? Thank you.
