Verification studies of blow molding software on ovalized parisons in extrusion blow molding

This paper is a study of ovalized parisons in extrusion blow molding simulation software. The software being used is BlowView. BlowView can be used to simulate the extrusion blow molding process and aids in reducing design time for accurate product thickness. BlowView is utilized to lower the development time when used correctly. This paper will compare the output from the simulated process to the actual manufacturing setup and results. Currently extrusion dies are being built using previous standards and educated guesses. Dies are originally built and usually needing of modification to produce the desired profile. With the use of the computer simulations, giving all the design considerations will accelerate the developing of the die and necessary process.
