Abstract: Parting-direction selection for die-casting parts is an important decision, which affects further downstream activities like manufacturing. Selecting a suitable parting direction in die-casting is difficult as it is influenced by many factors based on shape, topology and manufacturing process. Normally it is decided by die-casting experts. There is still no qualitative or quantitative method that considers all influencing factors. A comprehensive methodology to identify optimal parting direction for die-casting has been developed. Candidate parting directions are evaluated using Pahl and Beitz method. Comparison of results for many parts, with those obtained from industry has been found to be satisfactory.

Keywords: parting directions; die casting; Pahl and Beitz method; design-manufacturing integration; optimisation.
