The quality of die cast product and the economics of the process are critically influenced  by the prevailing technological conditions. To assist the designing of dies for small and medium die  shops, this study was conducted to develop a computer-aided design methodology that design  engineers can use to design the die casting dies. In this study general design rnles are presented for  various die casting alloys. A case study is carried out to present design methodology which will be  useful for small and medium die shops. Combination of bottom-up and top-down approach is  applied to design a die casting die for a water pump body. Flow analysis is carried out to  determine the flow pattern in the runner sections. Thermal analysis is also carried out to determine  location and size of cooling waterlines. Providing thermal control units with this design, the  optimal casting condition can be achieved. 0aComputer-aided design1 aBohez, Erik L.J.,eChairperson1 aDuflou, Joost R., eExamination Committee1 aPandey, Indra M.,eExamination Committee2 aThe Royal Thai Government, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
