3M Fused Silica Advanced Shell System GM2 is a high-performance, fiber-based flour blend for investment casting backup slurries. This dry blend of fused silica and high-performance additives offers increased shell build which, coupled with improved permeability, can help remove dips and minimize autoclave shell cracking.A Pure Product for Investment Casting
Designed for investment casting backup slurries, 3M Fused Silica Advanced Shell System GM2 is a fiber-based flour that can help remove dips as well as minimize autoclave shell cracking. This dual-purpose system allows an advantageous combination of edge build and corner build, while at the same time enhancing shell permeability -- thus cutting the total number of dips required while reducing positive metal scrap.
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.
