Jul 16, 20180183;32;In the lost foam casting process (LFCP), polymer foam models are molded into binder free sand and cast directly. The hot melt then decomposes the model. This casting technique using lost molds and models offers the greatest possible degree of freedom in the design of multifunctional castings, even without the use of sand cores.
Publisher Summary. In lost foam casting, the preforms of the parts to be cast are molded in expandable polystyrene or special expandable copolymers. Complex shapes can be formed by gluing moldings together. The preforms are assembled into a cluster around a sprue and coated with a refractory paint.

Lost Foam It is a casting process in which the pre expanded polystyrene foam is used to produce a steel, castiron or non ferrous casting of the exact same shape. 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.
