JST uses the latest computer numeric controlled (CNC) equipment available for punching, shearing and forming to fabricate enclosure panels, bus work and other components. In addition to the CNC equipment, JST has a fully equipped machining and welding center to perform all operations needed to completely fabricate enclosure components without using outside services. Upon completion of the machining stages, JST will provide the necessary finishes in a dedicated area with baths used for pickling. An extremely durable finish is applied by our electrostatic paint shop.
