Track: EXTRUSION/DIE, PRACTICAL - Recovery Improvement
ABSTRACT --- Extrusion defects such as streaking and surface roughness have
been studied and analyzed. The streaking is focused on die-related issues and
investigations are made to check the root cause of the problem. A study of die
design and an industry checklist established to overcome streaking are discussed.
