Abstract

A process for resin transfer molding (RTM) with injection and overflowing of a resin through one or more troughs is provided that includes the injection of resin into a plurality of injection ports feeding the one or more troughs and overflowing the resin in into a mold. The temperature and pressure are controlled as applied to the mold. The injection ports are activated for injecting the resin in any order of individually, in groups, or pairings. A resin transfer molding (RTM) system for performing the process includes a mold having a cavity. A set of injection ports feed one or more continuous channels between the cavity and a reservoir of resin. A numerical controller selectively activates the injection ports to overflow the resin into the cavity in any order of individually, in groups, or pairing.
