Resin Transfer Molding ProcessResin transfer molding is a closed molding process. Reinforcing material such as woven roving is pressed into a mold tool made of polyester, aluminum or mild steel. A second mold is pressed/clamped over first mold and resin is injected into the cavity. Vacuum assisted resin injection transfer allows the epoxy to displace air fully saturating reinforcing fiber matrices. Automated, fast, clean, repeatable process ensures consistent part thickness and short cycle times. Water tight composite parts feature high strength to weight ratio and good surface finishes. Master Bond offers products with the right viscosity, gel time and cure temperature for RTM processes.
