Are you looking to improve your foundry’s efficiency while prioritizing safety? Switching to Green Diamond Sand from Midvale Industries is a game-changer for both ferrous and non-ferrous operations.

Why make the switch?

Superior Surface Finish: Achieve a high-quality, professional casting finish without the risks associated with crystalline silica.
Zero Silica Exposure: Green Diamond contains no crystalline silica, helping your facility comply with PEL limits and ensuring a safer environment for your team.
Lower Scrap Rates: With low thermal expansion and high permeability, you’ll see a significant reduction in expansion defects and gas-related pitting, leading to less waste and higher yields.
Versatility in Sizes: We offer a wide range of AFS blends, including very fine sizes and custom pre-mulled options to fit your specific sand system.
