Application of computer simulation of thermoset resins casting in rapid

prototyping techniques (in English)

Summary

The article presents a methodology of the technological process to manufacture technical cast profile models based on the example of gear wheels in silicone molds produced with the vacuum casting (VC) method. In this process, designing of the model manufacturing begins with the preparation of the silicone mold structure. At this stage the properties of the material to be cast into the silicone mold should be taken into account. The properties, including the viscosity, density, reactivity and crosslinking thermal effect of the material should be build into designing of the prototype. They determine also the geometry of the runner system supplying mold cavity and its vents.
