Extrusion blow molding (EBM) is a widely used and known manufacturing process to produce thin or thick thermoplastic hollow object like cosmetics container or big drums. This process can be realized on extrusion blow molding machine and tooling. Each extrusion blow molding machine has a programming die head. The initial parison thickness distribution should be depended on final bottle geometry. However, to determine the proper distribution of parison thickness to get the most uniform thickness of the container wall, it is not an easy task. In order to precisely define this distribution is simple using Ansys Polyflow. The article includes a comparison of bottle wall thickness distribution obtain in real manufacturing conditions and in realizing Polyflow simulation. Also it will be propose an initial parison thickness distribution (programming) for the bottle design, which is manufacturing in the industry to pack nail polish remover. This will allow the packaging manufacturer to produce a bottle of a higher quality in terms of distribution of wall thickness.
