Profile: Built Rite - Reliance Engineering is an integrated plastic technology company with expertise in plastic part design, mold design, mold making, and plastic processing. We offer precision molds for liquid injection molding of liquid silicone rubber, injection molding of thermoplastics & thermosets, and compression & transfer molding of thermoset plastic materials. Compression molding of thermoset materials is a manual process that transforms granular material into a molded shape, by placing material into an open mold cavity, and then closing the mold. Thermoset transfer molding includes the additional process of pre-forming a pill of material before being injected into a closed mold via the mold's runner & gate system.
