Lost Foam

However, Kurtz has to offer much more in terms of moulding machines: the so-called lost-foam procedure or casting with lost particle foam models in binding agent-free sand is applied world-wide to an ever growing extent. The special know-how with regard to this procedure is to be seen in the design of the moulds. They are fitted with several integrated steam chambers, where each of these steam chambers is provided with a separate steam, air and water regulation facility.

The procedure is mainly applied in the automotive industry, e.g. for the manufacture of cylinder heads, brake disks, crankcases, oil pump casings and suction manifolds.
