Light RTM (Resin Transfer Molding) is a closed-mold system that consists of a mold or counter mold. The mold flanges incorporate seals that create an air-tight seal, ensuring a vacuum environment within the mold. Mold and vacuum pressure are applied to remove any air bubbles and ensure a uniform resin distribution, thereby reducing imperfections such as pinholes.The laminate stack of fiber reinforcements is placed in the mold tool, carefully aligned to achieve optimal structural integrity, depending on the orientation of the fibers. Once the mold is prepared, vacuum pressure is applied to the sealed mold to prevent air from entering or escaping.Catalyzed resin is then pumped into the mold through ports, typically located at the resin runner’s entry point. The resin is injected under pressure, ensuring an even distribution and minimizing porosity. As the resin flows, a resin runner is incorporated, which allows for the creation of a uniform resin flow pattern throughout the laminate stack.After injection, the mold is subjected to additional vacuum pressure to remove any excess air or bubbles that may have formed during the resin transfer process. The resulting part is then cured under controlled temperature and pressure conditions, resulting in a strong, lightweight, and durable composite material. RTM can be a real improvement over open molding, the tooling requirements must be considered.RTM can increase productivity with mold cycles using several base molds.
