CLASSIFICATION OF DEFECTS IN AUTOMOBILE WHEEL MANUFACTURING AND THEIR ROOT CAUSES

This article presents a comprehensive analysis of defect classification in automobile wheel manufacturing and the underlying causes of their formation. Particular attention is given to aluminum alloy wheels, where internal and external defects significantly influence mechanical performance and operational reliability. Based on a systematic review of scientific literature and analytical evaluation, defects are classified according to their nature, origin, and manifestation. The study further investigates metallurgical and technological mechanisms responsible for defect formation. The findings demonstrate that proper control of process parameters and understanding of defect mechanisms can significantly reduce defect occurrence and improve product quality.
