The molten metal is poured on to the top of the gating system, which is responsible for directing the molten metal through the cluster. Thanks to comprehensive further developments, large series are possible today with the LF casting process. During casting, the patterns remain in the compacted sand mould (full mould). The cost of production of these castings by the LFC process is much less relative to the conventional processes, such as sand casting. In most cases the pattern is molded in polystyrene (2.5% polystyrene and 97.5% air) in a closed mold. It is meant to address customer needs for ever more complex shapes and optimized production costs, in industries like railway, steel furnaces, etc. Centrifugal Casting, Die Casting, Lost Foam Casting, Permanent Mold Casting, Sand Mold Casting...

Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting with foam as the pattern. THE LOST FOAM CASTING PROCESS 2. The EPS positive patterns are mounted to a casting system. Lost-foam casting (LFC) is a casting method used to create solid metal parts from molten metal. Nach dem Schlichten werden die Modelltrauben in Gießbehältern eingesetzt, die anschließend mit ungebundenem Quarzsand befüllt werden. The Lost Foam Casting Process has come a long way since its first introduction in 1953, but in fairness after the first real production line in 1980; and over the past 30 years there have been considerable improvements, both in basic materials and the improved design of the equipment. Originally made with green sand molds and a core used to make the vents, the component ran into issues during machining, when the vents were obliterated. The heat from the molten metal will cause the polystyrene pellets to vaporize, resulting in the creation of a casting that can be ejected form the mold cavity. The process of pattern making can vary depending on the number of items that will be replicated. Evaporative pattern casting uses molds which will melt or evaporate upon contact with hot molten metal to generate intricate, complex metal parts. Utilizing the latest 3D data and molding technology, our team of technical professionals and supply chain partners can create a T6061 aluminum tool for any application. Lost-foam casting, however, is relatively simple and straightforward: The polystyrene pellets are injected into the mold cavity, after which molten metal is added. Together with lost-wax casting technique, lost-foam technology is a state-of-the-art method in the production of high-quality castings of complex shapes.
