【Abstract】By referring to the principle of vacuum metallization process，this arcitle investigates the mechanism of metallization layer peeling-off phenomena. From the perspectives of structure design，bottom painting，silicon oil，vacuum chamber parameters setting，aspect quality of injection parts and exterior environment，it studies the root causes of vacuum aluminum layer peeling-off and its countermeasures. It also proposes the assessment method of aspect quality on vacuum layers based on the on-line checking and testing. By practicing with one project，it proves the reasonability of these countermeasures and assessment methods.

【Key words】vacuum metallization；metallization layer peeling-off；vacuum chamber；reflecting ratio
