Due to the precision-casting-process, work-pieces from a few grams to 100 grams of weight can be prepared. The lot-sizes are variable. Even single pieces can now be produced easily and economically because of the the so-called “rapid-prototyping”. Rapid Prototyping, or also-called “Rapid Tooling”, is CAD-based, and means a "virtual"-production-series of identical prototypes or pilot-series can be generated. The computer simulation can significantly reduce the development time of a work-piece - an important competitive advantage for the user. There are no limits concerning the complexity of the casting, which in turn opens up new possibilities for the application in mechanical engineering. The CSSC Technical Products Ltd. relies increasingly on product-design (High-Density-Baler, Excalibur).
