IMR (In-Mould Decoration by Roller) in-mold decoration technology prints decorative and functional patterns onto the film using a high-precision printer. The foil is then fed into a specialized molding mold through a high-precision foil feeding device. After precise positioning, the pattern on the foil is transferred to the surface of the plastic product under the high temperature and pressure of the plastic raw material. During the production process, the IMR foil substrate serves as the pattern carrier, leaving no substrate on the product's surface.
