Germany's Krauss-Maffei (U.S. headquarters in Florence, Ky.) has teamed up with German moldtexturing expert Galvanoform to develop a process that combines K-M's PUR Long-Fiber Injection (LFI) process with Galvanoform's in-mold graining (IMG) technology. The result is the ability to produce longglass reinforced PUR parts with high-quality grained surfaces in a single mold by means of in-mold film decorating. The new aspect is thermoforming the film insert in the same mold used for LFI. The technique is aimed initially at automotive door-trim sections, glove-box lids, and instrument-panel surrounds. The IMG process uses special molds to create textures on decorative film inserts during thermoforming. The heated film is positioned in the mold, where it is held in place by a frame, negatively thermoformed and grained on the surface against the mold. The fi xing frame is retracted and the LFI mixing head sprays the PUR matrix with long glass onto the shaped and grained skin. The mold is closed while the PUR cures. Galvanoform's patented process reproduces even very fi ne leather graining in a porous nickel electroformed shell only a few millimeters thick, which is then integrated into a complete mold with temperature control and a vacuum system. Combining processes in one mold eliminates the possibility of distorting a grain that is embossed into the film in a separate step prior to thermoforming. Eliminating a separate embossing step also reduces cost, as does the ability to produce different surface grains using different molds but just one type of fi lm.
