KraussMaffei's (Munich, Germany) new RIM-Star high-pressure resin transfer molding (HP-RTM) production cell is designed for series production of carbon fiber-reinforced composite components that are paintable direct from the mold. The system will soon be used to mold roof shells, with a 50 percent fiber volume, for the Roding Roadster Targa (Roding Automotive GmbH, Roding, Germany). The polyurethane matrix resin will be prepared by two RIM-Star Nano 4/4 metering machines, which are equipped for high-temperature process control with material temperatures up to 80°C/176°F. The wear-optimized machine design reportedly will ensure permanent process stability with polyamide (PA), polyurethane (PUR) and epoxy resins. The machine’s centerpiece is a new RTM mold carrier with a compact design and a clamping force of 3,800 kN. The mold fixing area (1,300 by 1,300 mm, or 51.2 by 51.2 inches) is said to be ideal for auto components as large as 1m²/10.8 ft².
