No matter which process you choose—assembling panels from aluminum, steel or wood; hand lay-up with composites; or producing panels using the vacuum assisted resin transfer molding (VARTM) process—throughput remains low while costs are high. Our high fiber volume, glass-reinforced thermoplastic panels and continuous resin transfer molding (CRTM) thermoset sandwich panels can streamline production and reduce system costs by eliminating assembly steps such as welding, drilling, bolting and riveting. Because the manufacturing process is continuous, it also provides significant cost savings over traditional composite panel manufacturing techniques.
