Silicon carbide (SiC) ceramic foam filters designed for high-efficiency filtration of molten metals in foundry applications. These open-cell foam filters remove inclusions and reduce turbulence in the gating system, allowing cleaner, more laminar metal flow into the mold cavity to improve casting quality and reduce scrap.

Key features

  • High filtration efficiency: porous open-cell structure captures non-metallic inclusions and floating slag, producing cleaner castings.
  • Thermal and chemical stability: engineered formulation and sinter process deliver excellent thermal-shock resistance and chemical stability at temperatures up to 1500°C.
  • Mechanical strength: multi-impregnated slurry processing results in high-strength foam filters that resist breakage and avoid loose debris during pouring.
  • Controlled porosity and sizes: consistent pore structure and precise size control ensure predictable flow characteristics and minimal blockage during pouring.
  • Quality raw materials and process control: selection of high-grade feedstock and mature sintering technology for stable, repeatable performance.

Typical applications

  • Grey iron, ductile iron and malleable iron castings
  • Non-ferrous castings including aluminum, copper and bronze alloys

Benefits for foundries

  • Fewer casting defects from inclusions and turbulence
  • Improved surface finish and mechanical properties of cast parts
  • Higher first‑pass yield and reduced rework/scrap
  • Reliable performance in high-temperature pouring environments

Recommended use

Install the SiC ceramic foam filter in the gating system upstream of the mold cavity so molten metal passes through the filter cell structure. Select filter size and porosity appropriate to alloy type and pouring rate to balance filtration efficiency with flow rate.
