  • Demistifying RTM

    Resin Transfer Molding (RTM) is a low pressure, closed molding process which offers high-quality dimensional and surface finish composite moldings using liquid thermoset polymers reinforced with various forms of fiber reinforcements. Typically polymers of Epoxy, Vinyl Ester, Methyl Methacrylate, Polyester or Phenolic are used with fiberglass reinforcement.

    Resin Transfer Molding (RTM) is a low pressure, closed molding process which offers a dimensionally accurate and high quality surface finish composite molding, using liquid thermoset polymers reinforced with various forms of fiber reinforcements.

    The RTM process begins with loading dry fiberglass or similar reinforcement into the mold cavity. Once the mold is closed, the resin pump pumping both catalyst and resin simultaneously to the mix head, then mixes the resin and catalyst together as a single component and injects it into the mold until the mold is completely filled and the resin appears at the vent ports.

    The vacuum molding process begins with having loaded the cavity mold with fiber and then bringing the semi-flexible upper mold half into the cavity, making a closed molding cavity condition. The resin then feeds around the resin channel - around the parameter of the mold - and once the resin fills the channel, it then begins to enter the actual mold cavity.
