The tea sets come in various materials such as ceramics, glass, and purple clay. These products are prone to damage, color differences, and flaws. Therefore, it is crucial to conduct standardized inspection before shipment.
The inspection process begins by verifying the order information to ensure that the product model, quantity, color, and packaging specifications are consistent with the contract. Count the number of outer boxes and check for any errors or omissions in the labels and shipping marks. The key focus of the visual inspection is to examine the body of the teapot and the cup, looking for cracks, missing glaze, scratches, deformation, black spots, and color differences; also, check the completeness of accessories such as the lid, filter, and tea tray.
The functional tests include checking the tightness of the lid, the smoothness of water flow, and whether there is any leakage. Sampling checks are conducted for dimensions and weight to ensure they meet the tolerance requirements. At the same time, the packaging is randomly inspected to verify if the foam and gift box protection are adequate, to prevent any breakage during transportation.
Finally, make records, take photos to preserve the defective samples, calculate the defect rate, and determine whether the batch is qualified. Standardized inspection of tea sets helps to intercept quality issues in advance and reduce the risk of after-sales service.
