Sažetak

Many factors are responsible for the formation of surface and internal defects during copper wire drawing process. Generally they may be divided into defects of material or processing origin. Even input material of the highest quality with little to none defects cannot ensure the absence of breakages during the process due to inadequate process parameters. Optimally selected process parameters may reduce the risk of cracks forming during the metal forming process. The paper presents examples of wire defects and cracks occurring throughout the wire drawing process of copper in industrial conditions and a wide analysis of their source.
