发明名称 Method and machine for manufacturing molded structures using zoned pressure molding
摘要 A method for manufacturing a molded structure in a press that includes a first mold and a second mold is provided. The second mold has a plurality of pressure actuators, with each pressure actuator capable of independent operation. The method includes the steps of positioning a preform having a thickness in the first mold, placing a quantity of resin adjacent the preform so as to create a resin reservoir, and then selectively actuating one or more of the pressure actuators apply pressure to the resin reservoir to force at least a portion of the resin reservoir to infuse through the thickness of the preform. The method may also include curing the resin-infused preform, and then removing the cured resin-infused preform from the first mold.
