High-Speed Computer Tomography: Pressure Die Casting

For many years, molders have been trying to figure out the influence of diverse factors on the quality of die castings during molding. In 2010, the rapid computer tomograph became available for the first time. This system is derived from medical technology and offers new testing methods. The measures, which have been in progress for the past 5 years, were focused to point out the correlation between the major influences of pore expression in pressure die castings. These results are suggestive of the future technological and constructive work. Through continuous improvements in testing methods, the technology finally succeeded to work out major influences on pore expressions in pressure die castings. With these new findings, it is possible, and even proven by example, that through the right choice of process parameters strength-influencing pores can be reduced. In case of not preventing the formation of pores, they could be moved out of the areas, which are strength vulnerable. This is an appropriate concept to reduce the weight of components and therefore the implementation of lightweight constructions in the automotive industry.
