Extrusion blow molding using cylindrical-shaped parisons has been the process of choice for the production of plastic fuel tanks (PFT) for the automotive industry. A revolutionary process called twin-sheet blow molding is now recognized as an innovative technology for manufacturing PFT. BlowView~?, a commercial finite element software developed by the National Research Council Canada's Industrial Materials Institute, has now been adapted to simulate this new process type. It supports engineers to sketch and visualize PFT designs resulting from the twin-sheet process, before committing to expensive tooling in manufacturing. Optimization to improve quality, decrease cost, etc., is also under investigation.
