Sažetak
The paper deals with application of Six Sigma methodology in continuous improvement of aluminium die-casting process. Due to high level of aluminium castings scrap in die-casting process an Six Sigma project is started with main goals to reduce machining scrap from average of 4.12 to less than 2 %, and to reduce material scrap from high 11.43 to less then 4 % in average. The porosity is selected as major scrap type which contributes more then 80 % in total amount of scrap. Furthermore, parameters with major influence, defined in cause-and-effect diagram, are analyzed, improved where necessary, and put under control using Six Sigma tools and methods. Although, initial project goals are not completely met, major die casting process improvements are made, resulting in significance savings.
