We specialize in the manufacture of simple and complex Mica parts, and have a design and engineering team capable of supporting product development, design change and fulfillment. Our mica splittings plate production capabilities are further elevated by Proprietary and internally developed equipment that push fabrication options beyond the scope of other fabricated mica parts manufacturers. Building our Hot molded Mica Splitting plate in-house at our Virginia Facility gives us a significant advantage in controlling the quality of the product, being able to review process with our clients and then allows very low lead times.
