3M™ Fused Silica Advanced Shell System WDS3 is a dry blend of fused silica and high performance additives that are used for investment casting backup slurries.
Run Fast, Build Strong
Thanks to its unique slurry rheology, 3M™ Fused Silica Advanced Shell System WDS3 (PDF, 138.49 Kb) helps you increase foundry output. That's due to its ability to substantially shorten drain times — in turn shortening the investment casting process. Plus, since each foundry has different requirements, 3M fused silica advanced shell system WDS3 is engineered with built-in flexibility, and the slurry can be adjusted for specific application needs while simultaneously building robust shell thickness.
Optimized for Better Slot and Hole Coverage
Our fused silica advanced shell system WDS3 is a specially designed, high-performance product used for investment casting backup slurries. Its shell build provides uniform coverage of corners and edges while still addressing the flow needed to fill slots and holes in difficult investment castings.
A Pure Product
Our revolutionary furnace design helps prevent the raw silica sand from becoming contaminated during processing — resulting in a finished product that is 99.7% pure, while increasing productivity tenfold over conventional furnaces.
