The existing production methods for manufacturing of internal threads are suitable for producing detachable, high-strength joints in lightweight materials. Depending on the technology applied, there are process-related variations in the thread quality. Especially in the context of mass production of aluminum components, high productivity and quality are to be obtained. Innovative tapping technologies provide advanced process concepts, which allow minimized production times. In this study, the technical properties of internal threads are investigated in relation to the manufacturing process. By applying scientific valuation methods, the analysis of different tapping technologies for aluminum casting materials is achieved.
