Resin Transfer Moulding (RTM) is a low pressure, closed moulding process which offers high-quality results when dealing with composite mouldings of large dimensions. It does so by using a wide range of resin systems with fiber packs such as carbon, glass, aramid or a combination of these and other fibers, depending upon the characteristics desired in the finished product.

This technology offers the best option in terms of costs and performances, while overcoming the difficulties associated with medium and high volume production. Usually raw parts extracted from RTM moulds are cut with water-jet machines.
