- Three-dimensional Simulation on Parison Shape at Pinch-off Stage in Extrusion Blow Molding
抄録
In this study the parison shape at the pinch-off stage in extrusion blow molding was theoretically predicted by non-isothermal and purely-viscous non-Newtonian flow simulation using a finite element method. In this simulation, the angle of knife edge θ, the depth d and the length l of compression land of a blow molding mold were changed. The results obtained are as follows; The parison thickness at the bottom increases as the angle of knife edge and the depth of compression land decreases, but is almost independent of the length of compression land. The parison temperature on the parison inner surface near the pinch-off knife decreases as the angle of knife edge and the depth of compression land increases. The parison thickness at the bottom decreases as the mold closing time is shortend.
