摘要

A large growth area for blow molding is in automotive applications. The benefits of plastic for automobiles include (a) lower investment costs for plants and tooling, especially for high production volume, (b) ability to tailor the material to obtain desired barrier and chemical resistance properties and (c) reduced car weight and cost. Recent trends in blow moulding are towards the use of multi-layer sequential material processing. The introduction of multi-layer processing has contributed to increase the number of potential markets for blow molding. This study shows the effect of the processing parameters on the wall thickness distribution of each layer in the final multi-layer blow molded product. Some experimental results are compared to simulation predictions obtained by employing an integral viscoelastic material model (K-BKZ).
