Molds, frames, barriers, and production tools for metallurgy

Don’t let anything burn when it comes to metal casting, molding, and sintering

Benefit from our graphite and CFC materials that remain dimensionally stable even far above the melting temperature of most metals. They feature minimal thermal distortion and excellent thermal cycling resistance. These outstanding properties are achieved even with the thin walls of our solutions, leading to weight savings that enable you to achieve better hardness results, faster firing cycles, and more efficient use of your high-temperature furnaces overall.

Outstanding materials, well-thought-out solutions, and ideas with added value

Tools for continuous casting and components for aluminum casting

High-quality semi-finished products from non-ferrous metals and their alloys are mainly produced using the continuous casting process. Our continuous casting molds are a convincing tool as they remain dimensionally stable at high temperatures without the alloy reacting with the tool. In the preparation of aluminum melts, graphite rotors and shafts are used. For sintering plates and boxes, the use of the very light and stable CFC material offers significant advantages over graphite. In pressure sintering, our CFC materials are ideally suited for the challenging combination of high temperatures and massive pressure loads. A common feature of all our materials is that they do not contaminate your products.

Durafox® – innovative protection against carburization

At temperatures of around 1,050°C, many steels react with carbon, causing contact reactions and the formation of eutectics. This lowers the melting point of the metal. The consequences can be contamination of the customer's product due to material diffusion or even melting of customer components. Ceramic or fully ceramic coatings are therefore essential as a barrier between steel and carbon. Our oxide fiber composite materials (OFC) Durafox® Ceramics are characterized by high damage tolerance and thermal shock resistance. Depending on the material variant, they are designed for continuous use at temperatures up to 1,300°C. Unlike graphite and CFC, Durafox® does not oxidize, making it suitable for use under oxidizing conditions.

Durafire® – optimal results after oil quenching

When components are oil-quenched after heat treatment, the load carrier is also subjected to stress. With conventional materials, bubbles formed in the oil can cause cavitation and material removal. Additionally, oil penetrates the open pores of the load carrier. Subsequent processes such as tempering, washing, and drying are usually not able to remove this residual oil. As a result, when the load carrier is used again, the oil evaporates and soot forms. Durafire® Dense load carriers, on the other hand, are specifically designed to meet these challenges. The result is a durable material that leads to optimal results after heat treatment.

Molds

For our molds, we can optimally tailor the graphite materials and their processing to your requirements. We offer a wide variety of materials and finishing techniques, such as our patented PyC coating, which increases the lifespan of the mold and improves output when casting lead-free copper alloys.

Frames

We offer frames and load carrier systems in a variety of designs and materials, optimally adapted to your specific requirements. In addition to custom developments, standardized solutions for CFC grid systems, such as UniGrid®, are also available. For oil quenching, frames made from our Durafire® materials are particularly suitable.
