Use of simulation to reduction of faulty products

Abstract

Simulation as an analytical and expert system has increasingly more important role in the development process of new products. Producing of healthy castings without foundry errors is the big issue in modern foundries. Foundry simulation software can do a lot to help improve the disposition of castings, gating system and feeder system and it can assure good filling and solidification conditions and also produce healthy casting without the need of the old method "try and error". One can easily change a lot of parameters for filling and solidification and create the best proposal for production. It makes possible to get a wide range of information that allow reducing various adverse effects and processes in the early stages of design. Production by lost wax investment casting process is one of the advanced technologies of castings production. We can use this technology in the case of products with complicated shape or hard machinable materials. Computer simulation gives us the answers to the correctness of the designed construction. The article deals with the issue of application of computer simulation for analysis of quality castings production, as the main predictive tool for reduction of faulty products.
