Manufacturing of glass container is a complex process, since it is linked to a great deal of parameters and forming variables which are difficult to be measured. The Numerical Simulation represents a powerful analysis and prediction tool capable to conceive and create accurate, efficient and cost-effective designs, as well as letting obtain a better understanding of the forming process complexity and its final output: the glass container.. A good perception of the physical phenomena's developing during the forming process will allow to: Provide logic explanations and recommendations on the forming process Provide logic explanations and recommendations on the forming process Optimize current forming tools (mould equipment) Optimize current forming tools (mould equipment) Improve forming equipment settings. Improve forming equipment settings. Application Example: Mould and Glass Bottle Production Optimisation Bottle model EB Heineken: © Heineken

FEA allows to verify that a proposed design will be able to perform to the designed specifications prior to manufacturing or construction. The use of the numerical simulation to analyze forming activities presents significant advantages: Quick perception of systems operations Quick perception of systems operations Possibility of evaluating physical phenomena's which are not possible technically to measure due to Possibility of evaluating physical phenomena's which are not possible technically to measure due to – its speed of development – lack of instruments capable to measure parameters we want to evaluate. A numerical simulation of a virtual model is far less expensive than making a real prototype. The gain of time is an important aspect comparing to build and making test on the forming site.
