Our casting shop is equipped with two medium-frequency induction crucible furnaces, each with a capacity of 3 tons and a connected load of 2.5 MW. This allows the production of approximately 3,000 kg of liquid iron per hour. In 2024, the entire electronics and control system of the furnace installation were comprehensively modernized to the latest state of the art. Despite several weeks of downtime during the conversion, there were no limitations in customer deliveries – production continued without interruption thanks to careful planning and alternative capacities.
Material variety and standards
Cast iron is one of the most versatile and cost-efficient construction materials in metal casting. Depending on the microstructure, the material can be optimally adapted to very different technical requirements. The most common types are spheroidal graphite cast iron and flake graphite cast iron – two material groups that differ significantly in their properties and therefore each offer specific advantages for different fields of application.
Spheroidal graphite cast iron
Spheroidal graphite cast iron is a high-strength cast material in which the carbon is present in a nodular form. This combines the good castability of gray iron with high tensile strength, toughness and fatigue resistance. It is used wherever robust and durable components are required – for example in mechanical, automotive and plant engineering.

Flake graphite cast iron
Flake graphite cast iron is a proven design material in which the carbon is present in fine, lamellar graphite structures. This microstructure provides very good damping properties, high compressive strength and excellent thermal conductivity. It is ideal for components such as machine beds, engine blocks or housings where dimensional stability, vibration damping and cost efficiency are key.
Precise temperature control, batch monitoring, and spectral analysis ensure a consistently high melt quality. After solidification and shake-out, the castings are prepared for further processing.
Clean Further Processing
After solidification and shakeout, the castings are cleaned in the blasting unit. Sand residues, burrs, and adhesions are removed to create a clean surface for subsequent machining or coating processes.
