100% PROUDLY MADE IN THE USA | 11 Filtration Systems High quality aluminum is often selected for critical cast parts used in aircraft, automotive, and computer industries, as these growing markets require better quality, greater strength, and improved machineability. Filtration systems are powerful tools used to filter out inclusions, which reduces flaws, voids, and brittle planes of fracture. While reducing inclusions, the metal acquires increased fluidity, greater strength and ductility, improved machineability and better surface finish. All of those benefits lead to reduced tool wear, fewer rejects and less rework. Schaefer is a pioneer in the design and installation of metal cleaning systems. We use a variety of filtration media, each chosen to meet a specific need. Our filtration solutions include filter plates, filter tubes, filter beds and sparging gases. The basic Schaefer concept connects a highly efficient wet bath reverberatory melting furnace with a specially designed filter furnace. The reverberatory furnace provides low melt loss and high volume whereas the filter furnace delivers high quality, clean metal with very close and stable temperature control. Both furnace types can operate on the energy source preferred. ADVANTAGES: • Reduce Hydrogen — to eliminate impurities to produce clean metal. • Reduce Porosity — to make stronger parts. • Reduce Inclusions — to make better surfaces. FOR: We provide filtration systems for a variety of metal casters, high and low pressure die casters, and permanent mold, sand, investment and lost foam foundries around the world.
