Conditions quality of polimer models and tools for application in Lost foam casting process

Abstract

In this paper, the basic principles of tools construction for expanded polistyrene model production as well as the possibilities of their application for casting large series of complex casting by Lost foam process, are given. Tools for models production are specific and require special studying. Polymer for the production of the model needs to have required characteristics and especially the lower density. The price of tools production is high, but their duty cycle is long, and the casting quality and productivity of casting by this method are high.
