The blowing extrusion in mould is one of the most widely used techniques for the production hollow plastic product example: bottle, cosmetics container, fuel tanks etc. A significant factor in the design stage of new blowing product is the selection initial parison shape in order to obtain the best distribution of final wall thickness in bottle. In this case using Ansys-Polyflow software is very helpful. This paper presents the blowing container Polyflow simulation with high-density polyethylene (Borealis, BS 2541) under isothermal and non-isothermal conditions. In the present work was showed the impact of the initial parison diameter and their geometry distribution onto final wall thickness in the sample container. This series of numerical simulation with parison optimization was showed that initial parison diameter and geometry have crucial importance for uniform final wall thickness distribution and minimal bottle mass. Eleventh cases of blowing parison were considered. Initial parison diameter was 14 mm and final 34 mm (step 2 mm). Optimizing the thirty milimeters diameter parison profile thickness for allowed to eliminate excessive thinning in the corners of container wall and get minimal container weight. An established criterion for a minimum wall thickness (1 mm) in the final product was achieved.
