Injection Compression Molding

A numerical study for the simulation of melt in an injection-compression molding process by using moving grid is proposed in this paper. The fully three-dimensional Navier-Stokes equations are solved together with the front transport equation using a front capturing approach. Different from previous studies, the proposed model can take the movement of cavity through a moving grid approach. The melt filling of a disk is conducted to illustrate the applications of the proposed numerical model with several computations under different processing conditions. The numerically predicted results show the influence of compression time or compression speed in determining the molding pressure and the melt temperature.

Injection Compression Molding

Abstract Injection compression molding (ICM) is a hybrid injection molding process for manufacturing polymer products with high precision and surface accuracy. In this study, a 3D flow simulation was employed for ICM and injection molding (IM) processes. Initially, the process parameters of IM and ICM were discussed based on the numerical simulations. The IM and ICM processes were compared via numerical simulation by using CAE tools of Moldflow software. The effect of process parameters of mold surface temperature, melting temperature, compression force and injection time on clamping force and pressure at the injection location of molded 3D BJ998MO Polypropylene (MFI 100) part was investigated by Taguchi analysis. In conclusion, it was found that the ICM has a relatively lower filling pressure than ICM, which results in reduced clamping force for producing a 3D thin-walled polymeric part.
