• The paper introduces precise injection molding for miniature products by locally controlling heat flux and magnetic field in the cavity of two small injection molds in each injection cycle. The first 98×98×117mm size mold has small sensors and actuators for controlling temperature/heat flux/pressure/deformation around the cavity of a box shaped product in 30×15×6mm size with 1mm thick walls, and the second 98×98×122mm size mold has a magnetic field generator, a force sensor and a small ring heater for a φ3.5×3.4mm with 0.9mm thick barrel shape product. For example, we could improve the straightness of the box shaped miniature product from 20μm to 3μm.
