Manufacturing expertise in fiber composites For many years, KraussMaffei has been working with widely varying processes for manufacturing parts made of fiber-reinforced plastic (FRP). These processes have traditionally evolved from injection molding technology and reaction technology (PUR). Today our process portfolio ranges from injection molding of components with short-glass-fiber reinforcement to high-strength, lightweight parts with a complex mesh structure in a reactive matrix. We set the highest priority on manufacturing processes that are automation-capable.
