The researchers specifically targeted the distribution of glass in two bottles with very different shapes. The researchers discussed material parameters such as viscosity and thermal conductivity and how they arrived at the values they used. They also discussed engineering parameters including cycle time, wall friction, stresses, and heat transfer between the glass and the mold along with the effects of varying modeling parameters.
In the end, the researchers showed rather good agreement between the model and the finished bottles. Thus, they foresee their manufacturing partner Ramon Clemente being able to improve quality while also reducing the time and expenses of iterative development cycles.
