Main work
The filling operation is to fill the contents of finished cosmetics into containers, bottles or boxes respectively. The filling operation is completely controlled by the automatic filling machine. The operator's main job is to place containers, bottles or powder boxes for filling, and check whether the filling results meet the standards or are abnormal. Occasionally, products that cannot be filled by the machine need to be filled manually.
Making vermicelli: As for the packaging operation, the main work is to put the label into the outer box of the product and then put it into the factory packaging (three bottles, four bottles or six bottles in a box, which is convenient for warehousing calculation and ensures the safety of the product). At this point, the operator must also check whether the product meets the standards again.
