A1: Full inspection: OUPN has a specialized testing department for quality full inspection, to ensure that every product is 100% full inspection before leaving the warehouse.
A2: Oiling: The products that require oiled need to be oiled before they are packed.
A3: Sealing: Before bagging, the packaging personnel need to reconfirm that there is no problem with the product, then put the product into a sealed bag, and then use the sealing machine for sealing.
A4: Packing: After sealing, the products will be boxed, crated and finally packed into the warehouse. Note: If the product contains iron, aluminum and other metal products, the whole process needs to be operated with disposable gloves, so as to avoid hands touching the oil seal, resulting in oil seal rust, so as to avoid affecting the later use.
