“The experimental method utilized in this research was the application of composite-based additive manufacturing (CBAM) mold plates in the injection molding process. The mold plates comprised carbon fibers and polyether ether ketone (PEEK) matrix. Modifications were made to the mold plates post manufacturing in order to properly adapt to the rest of the injection molding die. A custom cooling system was engineered and integrated into the injection molding machine for the CBAM mold plates. The polymer processed in the injection molding cycle for this study was Lustran 348 acrylonitrile butadiene styrene (ABS). The result of the trials conducted in this research demonstrated that polymer injection molding with CBAM mold plates was feasible and comparable to metal molds. However, adverse effects noted from using these parts made via the CBAM mold plates were rougher surface finishes and high adhesion between the polymer/tooling surface interface. In fact, the adhesion was so great that upon removal of the part from the mold, some regions of the PEEK matrix were torn from the tooling surface leaving a visibly unsmooth manifold behind. Further research and applications of CBAM mold plates could demonstrate promise in replacing the expensive, subtractive computer numerically controlled (CNC) metal mold plates for relatively small cycles”--Abstract, page iii.
