Prevention of Seizure in Deep Drawing Using Plastic Die

Article Preview

Abstract:

In this study, deep drawing using plastic die was investigated to prevent seizure during forming. In the deep drawing process of aluminum and titanium sheets, seizure was found to occur during forming due to a high reactivity with other metals. For the prevention of seizure, plastic dies were used in this study. These plastic materials have a good resistant to seizing, since no seizure occurs in the contact surface of the metal and plastic material. Moreover, the effects of seizure and wearing die on the dimensional accuracy of drawn cups were examined using nylon die. The blanks used were pure aluminum, aluminum alloy A5052 and pure titanium. The blanks could be successfully formed with a water lubricant. To increase the dimensional accuracy of the drawn cups, deep drawing using fiber-glass-reinforced nylon and plastic composite steel die was also attempted. It was found that the use of plastic die was very effective in preventing of seizure.
