Compression Molding
Compression molding is a high-volume, high-pressure method suitable for molding complex, high-strength fiberglass reinforcements. Advanced composite thermoplastics can also be compression molded with unidirectional tapes, woven fabrics, randomly oriented fiber mat, or chopped strand.
Aurora Technologies, Inc. produces parts made by compression molding fiberglass reinforced polyester materials. These thermoset materials contain a catalyst that initiates curing under high heat and pressure.
SMC and BMC parts are produced for a variety of industries. Currently we are manufacturing parts that include laundry tubs, shower basins, structural frames, and a large number of electrical insulating parts.
Because our materials have good dielectric strength and high heat distortion temperatures, they are used in a number of electrical applications. Our resin systems can also be tailored to meet a large number of corrosion applications.
