Two-Stage-GITBlow - Modeling, Simulation and Optimization of Wall Thickness Homogeneity
The basic idea of the Two-Stage-GITBlow process is the combination gas-assisted injection molding (GAIM) and blow molding. A Preform is produced via GAIM and subsequently inflated inside the mold to create a larger thin-walled hollow space geometry. Aim of this paper is the derivation of material specific process settings that allow the creation of a homogeneous wall thickness distribution. This is achieved by developing a mathematical model for the prediction of the wall thickness homogeneity, as well as simulations of the transient temperature development inside the preform via Finite Elements Method. Finally, the results are verified with experimental findings.
