| description | The design and fabrication of the mold are costly for the injection molding
machine. Prior to the fabrication process, the prior to molding analysis is important
to investigate the flowability of molten plastic in the mold design. The pre-molding
analysis is carried out using simulation software, with the purpose to reduce the
fabrication cost and time. Numerical simulation has been proven as a good tool and
cost effective way for pre-molding analysis. Therefore, this research focuses on the
unsteady three-dimensional (3D) simulation of mold filling during the thermoplastic
injection molding process using ANSYS FLUENT 14 software. Common
Polypropylene (PP) and medical grade materials are considered in the study.
Commercial single screw injection molding machine (Battenfeld TM750/21 O) is used
to study the flow front advancement of the common polypropylene at different
injection pressures and melt temperatures ofa single cavity of the tray. GOTfFERT
Rheograpb25 Capillary Rheometer machine is employed to perform the experiments
on the rheological behavior of the polypropylene (i.e., shear rate and viscosity) at
different melt temperatures. The rheological results are compared with those
obtained by numerical simulation. |
