Automotive Industry: Urgent Needs For Lightweight And Green Manufacturing

KraussMaffei introduced Thermoplastic Resin Transfer Molding (T-RTM) technology, which can produce mixed-material automobile prototypes made of fiber, plastic and metal in a shorter molding cycle. The new metering system enables the on-demand supply of raw materials (caprolactam), and the production of near-net shapes minimizes the waste of carbon fiber materials and processing steps that can be used to process both glass fibers (white) and carbon fibers. The on-site molded prototype is a fiber-reinforced composite automotive structural part with metal inserts, and the production process takes only a few minutes. Obviously, thermoplastic (PA6) structural parts have higher impact strength and more ductile fracture characteristics than thermoset plastics. In addition, T-RTM has a higher fiber content and lower viscosity than injection molding processes, resulting in extremely thin parts. KraussMaffei’s T-RTM process integrates reactive processing equipment, thermoplastics, and transfer molding technology. It also has the advantages of continuous fiber, short cycle, weldability, and recyclability, enabling modern lightweighting. The perfect integration of production.
