N2 - High-aspect ratio micro and nanoscale polymer features are not easily replicated using injection molding, with polymer often adhering to the tooling surface. To improve the replication quality, the adhesion needs to be minimized by modifying the tooling surface and adjusting the heat transfer. However, it is not easy to solve it without major investment on me process. Therefore, a novel metal-polymer hybrid tooling for micromolding has been suggested as a future microtooling and evaluated with various tooling surfaces such as titanium, and aluminum. Parts were molded using polystyrene and replication quality was determined using optical profiler and scanning electron microscopy. Heat transfer analysis was done to compare me novel tooling with silicon tooling and cooling time optimization.
