Production   Diversity of production requirements calls for a wide range of production techniques.       Our melting plant with cupola furnace, electric furnaces and holding furnaces for duplex operation ensures the highest degree of flexibility. According to the product quality required in each case, the iron from the cupola furnace can either be poured directly or used as basic melt for alloyed grey cast iron or for spheroidal cast iron.   For Hasenclever & Sohn with their wide range of production techniques, flexibility is a paramount importance; this means shortening production times and lowering production costs while maintaining optimal product quality. A principle that pays off for the customer.
