Cup Test for Tinplate

The cup-bulge test is used to detect the ductility and adhesion of tinplate coatings. The principle involves fixing the specimen in a ring fixture and using a steel ball to press it until the coating cracks, measuring the bulge height. Its purpose is to evaluate the coating's resistance to cracking during deformation. It is applied in quality testing for metal containers such as cans and food packaging.
Selection
When selecting tinplate for the cup drawing test, considerations include matching the sample thickness with the standard, ensuring the stamping speed complies with inspection specifications, verifying that fixture dimensions are compatible with the sample, and confirming measurement accuracy meets the requirements for identifying the fracture point. The choice of coating type depends on the application scenario; for instance, food packaging requires corrosion-resistant plating. The maintenance status of the equipment affects the stability of the test.
