Drop in. Filter flawlessly. Cast with confidence.

Since 1984, our ceramic honeycomb filters have been the trusted choice for aerospace, investment casting, and precision foundries—delivering higher yields, cleaner alloys, and fewer defects/part without the hassle.

Investment Casting Filters

How We Elevate Your Casting Process

You’re under pressure: costly scrap, inclusion defects, and inconsistent results. Foam filters require prep, introduce debris, and defect rates climb. It’s time for a filter that works for you—not the other way around.

Stop battling inefficiencies.

Precision filtering that:

  • Requires zero cleaning—drop it in and pour. No prep, no dust, no contamination.

  • Delivers laminar flow, reducing turbulence-splash and inclusions while enhancing purity and strength.

  • Uses L3MM technology, blending zirconia-level performance with mullite-level cost—delivering 45% less scrap and 20% fewer re‑works, boosting throughput by 30%.

  • Withstands temperatures up to ~3200 °F, engineered for the toughest foundry environments.

  • Offers customization and flexible inventory control, tailored to your production needs—whether ramping up or scaling down.

The Science Behind the Magic:

  • Consistent flow rates ensure reliable solidification and mold fill.

  • Oxidation, splash, and trapped air are minimized for cleaner, void-free castings.

  • In demanding fields like aerospace, these filters reduce inspection failures, uphold tight tolerances, and maintain structural integrity.

EXPERIENCE THE ADVANTAGES OF LAMINAR FLOW

  • Enhanced Quality

    Our ceramic honeycomb filters induce laminar flow, ensuring superior removal of debris, slag, and inclusions from molten metal.

  • Improved Flow Stability

    Enjoy stable and fast molten metal flow, preventing oxidation, splashing, and air ingress for higher-quality castings.

  • Consistency

    Unlike foam filters, ceramic honeycomb filters offer consistent flow rates, minimizing variability and ensuring reliable solidification control during casting.

  • Reduced Splashing

    Laminar flow minimizes the 'splash' effect, enhancing casting integrity and reducing void inclusions for superior final products.

  • Enhanced Control

    Benefit from precise flow control and minimized flow variations, ensuring consistent casting quality from pour to pour.
