ABOUT Resin Transfer Molding
Technology: Resin Transfer Molding Services are composite parts manufacturing services which use low pressure closed-mold fabrication techniques to produce parts of carbon fiber, aramid fiber, fiberglass, etc. The molding process produces products with a smooth finishes on both inside and out. Resin transfer molding is a moderate volume production process.Easy scale up from prototype to productionLower tooling costs compared with compression moldingHigh fiber volumeMinimized air entrapmentGood tolerance controlled over open molding
Resin transfer molding uses male and female dies under vacuum to sandwich composite materials between them. After compressing the material, resin drawn through the compressed fibers permeates them. Resin transfer molding offers higher throughput rates than open molding but lower rates than compression molding.
Advantages: Resin transfer molding services offers better strength over open molding and two sided finishes
Limitations of Resin Transfer MoldingControl of resin uniformity can be difficultPreforms are often oversized to allow resin penetration to edges, meaning higher scrap rates and edge trimming over open molding
Applications: Resin transfer molding services can provide higher strength composite structures than open mold molding, with finished inside and outside surfaces.Aerospace componentsAlternative to die cast metal parts
