Foundrymax Ø100×22mm / 10PPI Silicon Carbide Ceramic Foam Filter – High‑Capacity Filtration for Demanding Casting Runs
In modern foundries, the trade‑off between flow rate and filtration efficiency often dictates yield and quality. Foundrymax’s 100mm diameter round silicon carbide foam filter resolves this dilemma by combining a generous filtration surface with a robust 22mm body, delivering consistent melt cleanliness even under high‑pouring‑rate conditions.
Crafted from high‑purity silicon carbide, this disc withstands molten metal temperatures up to 1500°C, making it equally reliable for gray iron, ductile iron, aluminium, and copper‑based alloys. The 10 PPI open‑cell architecture strikes a practical balance: it captures coarse inclusions (slag, dross, and refractory debris) without creating excessive back‑pressure, so you maintain smooth mould filling and reduce the risk of misruns.
Coupled with the circular shape, which fits neatly into round sprue wells or pouring cups, the filter intercepts contaminants at the very entry of the gating system – where they are most harmful. The result is cleaner metal entering the cavity, which translates to fewer porosity defects, higher tensile strength, and a noticeably better surface finish on finished parts.
Beyond its physical attributes, this filter offers operational predictability. Its uniform cell structure ensures that every batch behaves identically, so you can fine‑tune your process with confidence. Whether you are casting large pump housings, valve bodies, or automotive components, this 100mm disc provides the capacity and durability needed for consistent quality across long production runs.
Why Foundrymax for this filter?
We are not just a supplier – we are a manufacturer with full control over sintering, cutting, and inspection. This allows us to offer the Ø100×22 size in multiple PPI grades (10, 15, 20, 30) and thickness variations on request, all with short lead times. Our technical team can also advise on positioning and gating design to maximise filter effectiveness. Factory‑direct pricing and sample availability make it easy to validate performance on your own shop floor.
