20 PPI 450x450x50mm Silicon Carbide Ceramic Foam Filter

Foundrymax 450×450×50mm / 20PPI Silicon Carbide Ceramic Foam Filter – Engineered for High‑Integrity Large Castings

Manufacturing large castings presents unique challenges: longer fill times, larger melt volumes, and greater vulnerability to inclusion‑related defects. Foundrymax’s 450×450×50mm silicon carbide ceramic foam filter is engineered specifically for these demanding applications, providing substantial filtration capacity in a format that integrates seamlessly into large‑scale gating systems.

The 450×450mm footprint offers a generous filtration surface suitable for high‑throughput pours, while the 50mm thickness delivers exceptional mechanical strength to withstand the thermal shock, erosion, and static pressure associated with heavy‑section iron and aluminium castings. The pore structure provides a balanced approach: fine enough to capture medium‑sized dross and oxide films, yet open enough to maintain good flow rates without excessive back‑pressure. This balance is particularly beneficial for large castings where both cleanliness and fill speed are critical.

Why Foundrymax for this large‑format filter?
Filters of this size demand specialist manufacturing capability – controlled sintering, precise cutting, and rigorous inspection. As a direct manufacturer, we produce the 450×450×50 size on a made‑to‑order basis, allowing us to maintain tight dimensional tolerances and consistent material properties. Alternative PPI grades (10, 15, 30, 40) and thicknesses are available to match specific casting conditions. Our technical team can also assist with gating design recommendations to maximise filtration effectiveness.
