Precision Resin Coated Sands for Critical Foundry Applications

A venture by practicing foundry personnel — two decades of expertise in shell core and mould making for the most demanding casting applications.

Resin Coated Sand

Exclusive RCS grades engineered for critical applications, with lower expansion grades to prevent veining defects in shell cores and moulds.

Anti-Veining Solutions

Authorized distributor of Prince Minerals LLC, USA — proven compound eliminating veining defects in complex ferrous and non-ferrous castings.

Special Purpose Sands

Chromite, ceramic, and high-strength low-density sands for specialized applications including binder-jet 3D sand printing.

What We Do

Two decades of foundry expertise, engineered into every grain

Samarth Metallurgicals combines hands-on foundry experience with state-of-the-art resin coating technology. Founded by practicing foundry personnel, our team understands the critical demands of shell core and mould making — from base sand selection to resin chemistry to process optimization.

As part of the Samarth Magna Group, we specialize in promoting innovative products, concepts, and services in foundry process and technology. Our in-house foundry enables real-world performance testing before every delivery — results your production line can count on.

Our customer base spans major casting manufacturers across India, supplying solutions for automotive, heavy engineering, and precision casting applications.

Why Choose Us

Built by foundry people, for foundry people

Our technical depth spans the entire shell sand value chain — raw material sourcing, coating process, and foundry performance validation.

In-House Testing

Our own foundry enables real-world performance testing of every sand grade before delivery — results you can trust, not just lab numbers.

Technical Expertise

Deep knowledge across base sands, resins, minerals, and foundry processes — with dedicated resources for complex defect prevention.

Warm & Hot Coating

Equipped with both warm coating and hot coating processes — combined capacity exceeding 5,000 MT per month for reliable supply.

Sand Reclamation

State-of-the-art infrastructure for sustainable waste sand reclamation — reducing environmental impact and material costs.

Our Process

From a single grain to a defect-free casting

Every batch of Samarth sand goes through the same five controlled steps. Scroll through the journey.

Step 01 · Base sand

It starts with the grain.

Washed, AFS-graded silica — purity, grain shape, and fineness number verified in our own lab before anything is coated. A weak grain makes a weak core; we reject it here.

Step 02 · Resin coating

Every grain, evenly wrapped.

Warm and hot coating processes apply a precise resin film around each grain — coverage, flowability and cure profile tuned to your application. Combined capacity exceeding 5,000 MT a month.

Step 03 · Shell core

Shot, cured, inspected.

Coated sand shoots into the core box and cures into a thin, strong shell — complex geometries, thin walls, and tight tolerances that green sand simply cannot hold.

Step 04 · The pour

1,400°C. The shell must hold.

Molten metal meets the core. Controlled thermal expansion, low gas evolution, no veining — this is the moment where premium sand pays for itself, casting after casting.

Step 05 · The result

Clean knockout. Zero veining.

Smooth finish, dimensional accuracy, defect-free internals — validated in our own foundry before the sand ever reaches yours. That is the Samarth standard.
