Melt Behavior Simulation on the Planetary Gear Pump Used for Polymer Differential Injection Molding (DIM)

Abstract:

A planetary gear pump (PGP) was introduced to the differential injection molding. The system is matched with a vertical injection molding machine (IMM). The PGP is integrated in the stationary mold and is fixed between the stationary platen and the movable mold of IMM. The dynamic mesh technology in the software packages Fluent was applied to investigate the melt behavior. Characteristics of the PGP, such as pressure and injection volume, used for the DIM process were studied
