At present, increasingly high demands on the quality of the manufactured castings, which are used in the automotive industry. The foundry respect there are a number of advanced technologies, which are used for the casting. These include the technology of production castings by investment casting. It is used particularly where in view of the complex shape casting technology is the production of other more expensive, respectively, it is not at all possible. Such casting is the rotor of the turbocharger to be used in...

In a large competitive environment in which today foundry exist are more important is production of castings with high quality and high economic efficiency. Therefore, the use of 3D software and simulation programs is necessary in the pre-production stages. In them it is possible to design, construct and simulate filling and solidification of castings in the foundry mould, design ingate system and feeder system. A properly designed and calculated ingate and feeder system is the first prerequisite for producing of ...
