Resin Transfer Molding
Benefits of Resin Transfer Molding
RTM has several benefits when compared to other available processes, they include:
What is Light Resin Transfer Molding or LRTM?
Light Resin Transfer Molding or LRTM is similar to RTM above. The main difference is how the resin is injected into the mold.
RTM uses a diverging flow when injecting resin into the two mold halves. This means the resin is injected in the center and flows out from the center to vents located on the corners or outer side of the mold. One of the biggest concerns with RTM is avoiding dry spots. LTRM solves this concern.
Light Resin Transfer Molding uses advanced tooling to allow the resin to be injected at the mold’s outer flange along the perimeter of the part and allows it to converge to the center of the mold. This differs from RTM in that with traditional RTM, you don’t want the resin to race around the edge while with LTRM it is designed to do exactly that. This eliminates dry spots and creates a higher quality part.
