Foundry technology places high demands on the materials used in moulded and machine components. In particular, these materials must be temperature-stable and must not react with the molten metal. Technical ceramics offer ideal solutions for these requirements and contribute significantly to the efficiency and durability of foundry systems.
Requirements for materials in foundry technology
The materials used in foundry technology must fulfil two essential requirements: They must be able to withstand high temperatures and rapid temperature changes and must not react or interact with the molten metal. These properties are crucial for the quality and durability of the moulds and machine components.
Technical ceramics in foundry technology
Materials such as silicon nitride are particularly important for foundry technology, as these materials offer outstanding thermal properties. Depending on the casting material and casting process, these materials can utilise their specific strengths to increase the efficiency and safety of casting processes.
