Fusite BV, part of the Emerson group, is specialised in the production of glass to metal seals. This technology is used to create electrical feed troughs that require specific chemical resistance and air tightness. Their largest market, at this moment, is the application of glass to metal seals in refrigerator compressors, for which Fusite is the global market leader. The same technology is used in countermeasures, flares and chaff, fired to mislead incoming missiles. Fusite entered the defence market through an offset program initiated by one of the market leaders in flare production. Delivering the flare housings of ignition cartridges Fusite now focuses on market expansion in countermeasures and pyrotechnics. Ignition cartridges This assembly is the primary component to a variety of electrically stimulated initiation devices. It consists of a metal outer ring and a center pole and these are completely separated by glass insulation. Spanning the inner and outer conductive parts is a very fine 1 Ohm bridge wire. When a suitable electrical current is passed through this bridge wire, it heats up and if in direct contact, can initiate a suitable pyrotechnic compound. Our customers/use This product has two primary uses: In the defense industry as an initiation device for a variety of pyrotechnic products. In the automotive industry as an initiation device for air bags. Customized glass to metal seal Fusite offers high quality Glass to metal seals, components and assemblies in accordance with our customer's designs and specific requirements. Production volumes can range from single units to mass production of millions. Lapped surface for optimized flatness and surface finish Among Fusite's capabilities is lapping of the glass-to-metal seal surface for a flatness below 0.001 mm and surface finishes of Ra 0.8 µm and lower. This secures a safe and reliable charging process for the pyrotechnic compound. Bridge wire welding Fusite adds value by welding the bridge wire onto the glass to metal seal to achieve a customized electrical resistance rating. Fully automatic processes guarantee a high process capability within tight tolerances, with 100% automatic testing included. Press fitting or welding into customized housings Fusite provides resistance welding and press fit processes to assemble the glass to metal seals into customized cartridge cases in house. Among other, housings can be from Aluminum, stainless steel and Nickel plated cold rolled steel. Surface coatings for high end corrosion protection in accordance with MIL standards Fusite offers high end coating or plating of components; Aluminum Chromate plating per Def. St. 03-18 and high corrosion resistant Nickel plating. Global Manufacturing As part of Emerson, Fusite has access to a global network of world class leaders and competitive suppliers. Together with Fusite's global manufacturing presence and commitment to quality Fusite can serve the needs of even the most demanding applications. [Detailed introduction] Latest Products |
