The Double-sided IMR process involves printing decorative and functional patterns onto a foil film using a high-precision printer. Through a high-precision dual-sided foil feeding device, the foil film is accurately positioned into a specialized forming mold. Under high temperature and pressure, the patterns on the foil film are transferred onto the surface of the plastic product. The IMR foil serves as a carrier for the patterns during production, leaving no base material on the product surface.
