Abstract
We investigated the in-mold coating process that can not only offer a superior surface quality of molded parts but also reduce environmentally harmful chemical releases compared with conventional coating processes. Polycarbonate (PC) plates were first fabricated via injection molding and then a coating layer was generated on the top of the plate in the mold cavity. The in-mold coating process was simulated numerically. To look into the effect of the coating, we prepared three different samples including pure, bar-coated, and in-mold coated PCs and analyzed their physicochemical properties. It turned out the samples prepared using the in-mold coating process had enhanced surface properties such as surface modulus, hardness and pencil hardness.
