Title：What important properties should be paid attention to when the aluminum cover comes into the factory 2020-12-14
Through the proof test, the aluminum cover needs to go through the high temperature link, if the high temperature resistance is poor, it is easy to appear deformation or fracture and other phenomena. Through the coating firmness test to verify, for the outer surface of the coated aluminum cover, if the heat resistance or corrosion resistance of the coating is poor, it is easy to appear wear, fall off and other problems.
Through the compatibility test, the barrier and sealing of the overall package of the container are largely determined by the compatibility between the container and the aluminum cover, including the evenness after the aluminum cover is installed and the aluminum cover is not deformed or broken after heating treatment. Therefore, if the poor compatibility of aluminum cover, it will easily lead to leakage and deterioration and other problems.
Through the bridge breaking force, breaking force, full opening force, tear force and other tests to verify, prevent the aluminum cover due to the opening force is too large, which will bring inconvenience to use, or the opening force is too small, aluminum cover and the container poor tightness, and leakage.
