Investment Castings

The Wastewater Challenge in Precision Casting

From ceramic shell cleaning and alloy finishing to post-cast surface prep, each stage of the investment casting workflow produces complex wastewater streams. These wastewaters often contain a mix of dissolved metals, fine particulates, and pH imbalances — making traditional treatment systems inefficient and prone to heavy sludge buildup.

Non-compliance not only risks environmental penalties but also operational downtime. As sustainability and traceability expectations rise across global supply chains, foundries and casting facilities must adopt automated, closed-loop wastewater solutions that maintain reliability and reduce waste.

Metafix’s automated treatment systems bring precision and control to investment casting wastewater management. Our solutions are engineered to remove heavy metals at the source, minimize waste, and keep your operations running smoothly — all while ensuring environmental compliance.

RT3

Advanced Rinse Treatment

Target contaminants: Cr, Cu, Ni, Ag
Cut costs with no hazardous sludge removal
Treated output with heavy metal concentrations of < 1 ppm
Integrated Metatrax remote monitoring
Modular processing speed starting at 8 L/min

RW3

Rinse Water Optimization

The Metafix RW3 brings automated precision to rinse water control in investment casting. It continuously monitors conductivity, pH, and temperature to maintain ideal rinse conditions, adding water only when needed to reduce waste and protect part quality. Its pump-less air-driven system prevents cross-contamination between baths, ensuring consistent, high-grade finishes while lowering water use and sewer costs — a smart, compact solution for cleaner, more efficient casting operations.
