STRUCTURAL ANALYSIS AND PETWALL PROFILER®

SIAPI, in collaboration with COMSOL, has developed study models for the numerical simulation of finite elements of PET containers. Siapi decided to use this tool in order to combine the design of a container with the simulation of its performance and, in this way, optimize the system while reducing the need to prototype the applications. The performance simulation of a container makes it possible to verify the limits and the criticality of the container, anticipating problems and identifying appropriate design solutions.  This process ensures the reduction of costs and prototyping time. Another advantage of the application of structural mechanics is the ability to provide customers with a detailed analysis of simulation and a list of causes that led to the variations from the original project in order to achieve the required specifications. For Siapi, Structural Analysis improved especially the manufacture of large capacity containers or Special containers. Furthermore, when we move to very low bottle weight, the bottle design it self is not sufficient to guarantee good bottle performance. It is absolutely necessary to consider the complete process, including preform design and process parameters, to achieve a consistent minimum wall thickness necessary to prevent bottle deformation.  For this reason, Siapi is working with AGR by using their PETWall Profiler® applied to large size bottles to manage the production process to a very fine wall thickness control in order to keep the bottle profile close to the target.
