Abstract
A method and apparatus for liquid thermoset resin or polymer molding using electromagnetic waves (particularly radiofrequency waves or microwaves), is described. The method and apparatus uses a metal mold (10, 212) with a cavity (401) for the molding as well as for confinement of the electromagnetic waves. Multiple low loss ports (A, B, C, D, E, p1, p2, p3) are provided for introducing the microwaves into the cavity.
