Precision Grey & Ductile Iron Castings Foundry

High-Thermal Bentonite Blend for Improved Foundry Productivity with Precise Casting Weights

Project Overview

Region

Eastern India

Industry

Leading foundry manufacturing high-precision grey and ductile iron castings up to 150 kg (DISA horizontal flaskless line, 2,500 MT capacity) – serves automobiles, pipe fittings, railways, earth movers

Engineering Focus

Casting bulging issues and rejection due to scab and sand inclusion.

Solution

Sandiron – engineered bentonite preblend combining imported and Kutch-based bentonite for high WTS and GCS.

Goal

Minimizing Casting Bulging with Advanced Bentonite Blend Technology

Outcome

Weight reduction: 1.35% on BD-XYZ, 1.6% on BD-ABC Abex.
Rejection reduction: 0.66% on BD-XYZ, 4.46% on BD-ABC Abex.
Improved casting quality with reduced defects and better dimensional accuracy.

Net result: ₹1.14 per kg net saving on casting, for 1,310 MT of production — a technically and commercially effective solution.
