Investment Casting

Castings inspected. Silver recovered.

Investment casters X-ray their critical parts in-house. Metafix recovers the silver from their film chemistry and treats the silver wash water.

The challenge

The hidden waste stream.
In casting inspection.

Castings for aerospace, energy and medical customers are radiographed to find porosity, shrinkage and inclusions before they ship. Many foundries run their own film radiography departments, and every film processed leaves fixer and developer saturated with dissolved silver, followed by wash water that carries what is left.

Silver is a regulated heavy metal and a valuable one. The MBX family recovers 99.99% of the silver from fixer and developer with no chemicals and no toxic sludge. Where silver wash water needs treatment, the RT3 brings it under 1 ppm before it goes to drain.

questions answered.

Need something more specific? Talk to our team or email sales@metafix.com.

Why do investment casters need silver recovery?

Casters X-ray their parts in house, and film processing leaves silver in the fixer, developer and wash water.

Which Metafix system do we need?

An MBX unit for silver from casting-inspection film chemistry. The RT3 handles silver wash water only.

Do we get paid for the recovered silver?

Yes. Filters come back to Metafix for refining, and we pay you for the silver recovered.

How clean is the treated wash water?

The RT3 treats silver wash water to under 1 ppm, ready for drain.

Are chemicals or sludge involved?

No. Treatment is chemical-free and produces no hazardous sludge.
