Lite RTM, A Green Process


New Boston RTM is leading the evolution of Low-pressure RTM, also known as Lite RTM, or LRTM. In LRTM, resin is transferred using a vacuum-assisted, low pressure injection system. Lite RTM requires less pressure, which means mold engineering is easier, and the reduced injection pressure results in lower environmental emissions.
