For a clean environment! Feed with us In line with our standard low-fluorine formulas, we now offer you a fluorine-free alternative, too. No fluorine in your sand system thanks to our exothermic fluorine-free minirisers and caps. Less problems with the disposal of your moulding sand when you use our fluorine-free risers. High casting qualities, since surface flaws normally caused by fluorine do not occur. Cost-saving production with our fluorine-free risers - even with highest quality demands. |

LÜ KinG ® The power exerted by high-pressure and impact molding lines were a new challenge for the AS LÜNGEN Company. An increasing number of foundries complained that this power was leading to damaging and destroying the risers, breaker cores and exothermic riser necks during molding operation. AS LÜNGEN therefore developed the BKS Riser LÜ KinG, a patent for which is pending. Pre-condition is a distribution of power between the riser and the molding sand. The riser is placed on a spring pin or a fixed pin. Before the molding operaton, a metal sleeve is placed together with the riser between pin and sand. The riser then shifts downwards on the pin during the compaction. The breaker edge is made of green sand. There is no longer the need for breaker cores and exothermic riser necks which are likely to be damaged by high pressures. During the development of the BKS technology it became clear which additional advantages are offered by this technology:
