Abstract: A mechanical system for inmold micro assembly molding was proposed. A theoretical model was formulated to describe the mechanism of thermalfluidstructure coupling deformation in polymer inmold micro assembly molding. Through finite element numerical simulation, the influence of the die wall temperature on the inmold micro assembly was studied. It was found that the micro assembly was controlled by its thermalfluidstructure coupling pressure field and inhomogeneous temperature field, and its microassembly thermalfluidstructure coupled deformation increased with increasing die wall temperature. Reducing of die wall temperature would help improve its micro assembly molding precision.
