“…Parallel to this work, Biosca et al [ 13 ] worked on the blow of glass bottles using the Ansys Polyflow finite elements (FE) approach. This study proved that viscosity was a key parameter to be correctly modelled as a function of temperature and shear rate.…”

Nanopattern replication of complex structures by plastic injection is a challenge that requires simulations to define the right processing parameters. Previous work managed to simulate replication for single cavities in 2D and 3D, showing high performance requirements of CPU to simulate periodic trenches in 2D. This paper presents two ways to approach the simulation of replication of complex 3D hydrophobic surfaces. The first approach is based on previous CFD Ansys Fluent and compared to FE based CFD Polyflow software for the analysis of laminar flows typical in polymer processing and glass forming as well as other applications. The results showed that Polyflow was able to reduce computing time from 72 h to only 5 min as desired in the project. Furthermore, simulations carried out with Polyflow showed that higher injection and mold temperature lead to better replication of hydrophobicity in agreement with the experiments. Polyflow simulations are proved to be a good tool to define process parameters such as temperature and cycle times for nanopattern replication.

Blow and blow forming process for glass bottle is already validated for 2D axisymmetrical bottles. Current research evaluates the capabilities of the 3D simulations with more complex geometries. This article presents the results of a numerical and experimental study of a non-axisymmetrical glass bottle. In this study, a perfume bottle with a square-based prism geometry and a new set of industrial process conditions have been evaluated. To validate the numerical results, the predicted temperatures in the glass domain have been correlated with experimental infrared measurements of the glass at various stages of the forming process. A comparison of the predicted glass thickness distributions with the section profiles obtained from the manufactured glass bottles is also provided. Finally, transition from the 2 Da to 3D model resulted in new difficulties and capabilities that are also discussed. This study validates simulations with experimental results to help in the design process of molds to avoid undesired thickness distributions and even fracture of glass containers for low thickness 3D corners.
