Vacuum solutions engineered for foundries & casting

The industry that runs the oldest dust hazard and the hottest floor at once — silica sand cycling from mold to shakeout to reclaim, reactive metal fines where aluminum and magnesium pour, heavy-metal exposure streams in the alloy shops, and a cooled-material rule that earns its keep every shift.

Foundries & Casting production process explorer

Every stage. Every challenge. The right vacuum solution.

Sand and metal trade places all day in a foundry — and each hand-off sheds its own dust. Walk the stages from mulling to furnace maintenance to see where the program earns its keep.

Stage 01 — Sand system & mulling

Silica sand, binders and returns mix continuously — mullers and transfer points shed quartz fines onto everything nearby, and the recovery rotation starts here.

Key challenges

The oldest dust hazard on the hottest floor

  • The Silicosis Record

    Foundry work is the historic silica industry — the disease record here predates the standards that now govern it.

  • Shakeout Concentration

    Freeing castings from molds is the exposure peak of the plant — burned sand and quartz fines at their finest and most airborne.

  • Reclaimed Sand Gets Finer

    Every reuse cycle mills the sand — reclamation concentrates the respirable fraction as a feature of the process.

  • Everything Is Hot

    Pour floors, castings, slag and spills — the cooled-material verification rule does real work every single shift.

  • Reactive Metal Fines

    Aluminum and magnesium casting shops carry combustible-metal rules on top of the silica program — two hazard systems, one floor.

  • Heavy-Metal Exposure

    Leaded brass and bronze, chromium and cadmium streams make sealed HEPA handling an exposure obligation, not a preference.

Representative case study

Controlling Silica Sand & Reactive-Metal Dust in a Foundry

How a representative jobbing foundry runs housekeeping on the oldest dust hazard and the hottest floor at once — silica sand keyed to the exposure standards while shakeout concentrates the respirable fraction, and reactive-metal casting cells carry their own combustible-dust rules on the same shop floor.
