Extruded ceramic honeycomb pressed filter

Extruded honeycomb ceramic filters manufactured from mullite-based ceramic for molten-metal filtration. The open-cell, engineered cellular structure captures non-metallic inclusions, reduces turbulence in the flow and provides a controlled balance between filtration flow rate and mechanical strength. The material and design deliver high thermal stability, dimensional accuracy and chemical resistance for demanding ferrous and non‑ferrous casting processes.

Key benefits

• Effective removal of slag and inclusions to improve casting integrity and surface finish
• Engineered cell structure to reduce metal turbulence and promote smooth fill
• High thermal-shock resistance and working temperature tolerance for heavy pours
• Good chemical resistance to acidic and alkaline environments
• Precise dimensions and repeatable performance for automated and manual gating systems

Typical applications

• Filtration of molten iron, steel, aluminum and non-ferrous alloys in foundry casting operations
• Use in gating systems, runners and pour cups where inclusion removal and flow conditioning are required
