Plastic caps are widely used in container packaging. Before shipment, conducting thorough inspection of the goods can effectively prevent quality issues such as size deviations, cracking, and improper assembly.
After arrival, first verify the product information to ensure that the model, material, color, quantity are consistent with the order requirements. Check the packaging labels and outer box marks to see if they are standardized and complete. The key point of appearance inspection is to check the surface, looking for burrs, scratches, deformation, missing materials, stains, color differences, and whether the edge of the cap is smooth without burrs.
Function testing is a crucial step. Sample matching assembly tests are conducted to verify the opening and closing of the corresponding container, the tightness of the screwing, and check the sealing performance. Check for any loosening, slipping, or leakage. At the same time, measure key dimensions, including outer diameter, height, and thread specifications, to confirm compliance with the drawing standards.
Also, verify hardness, temperature resistance, and other related requirements. Observe for any brittle cracking phenomena. Finally, check the packaging condition to ensure that the plastic cap is properly protected and the outer box is free from damage and moisture. Truthfully record all inspection results, organize the inspection report, and ensure the quality of export shipments.
