Sandiron Overview

Overview

SANDIRON is a powerful blend of high-thermal durability, imported bentonites, and premium Indian Kutch-based bentonite, expertly engineered by MPM Private Limited.

As leaders in green sand additives, MPM developed SANDIRON to improve surface finish, prevent sand sticking or fusion, and enhance mould integrity, delivering more precise casting weights.

Benefits

Enhanced Mould Strength

Boosts Green Core Strength (GCS) for stronger and more durable moulds.

Superior Sand Quality

Reduces Friability (Green Sand Strength or GSS), helping maintain stable sand properties.

Fewer Defects

Minimizes sand inclusions for cleaner, higher-quality castings.

Smooth Surface Finish

Prevents scabbing WTS(Wet Tensile Strength), maintaining a cleaner casting surface.

Improved Hot Strength

Reduces mould dilation to help achieve precise casting weights.

Efficient Bentonite Use

Lowers bentonite addition while controlling moisture demand and reducing waste.
