Infrastructure Access Solutions Foundry

Delivering Consistent Casting Performance on Vertical Molding Lines

Project Overview

Region

Eastern India

Industry

Largest manufacturer-exporter of iron castings from India (ISO 9001, EN 124, Kitemark, MPA Germany certified) – infrastructure access solutions: manhole covers and tree grates

Engineering Focus

High mold rejection %, inconsistent surface finish, and dimensional accuracy issues on the vertical molding line.

Solution

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

Goal

Driving Casting Excellence on Vertical Molding Lines Through Engineered Bentonite Technology

Outcome

Foundry rejection reduced from 1.7% to 0.48% (71% reduction).
Shot blasting time reduced from 6 min to 4.5 min (25% reduction).
Casting weight reduction achieved: 2%.
Surface finish enhanced from 4 Ra to 12 Ra (88% improvement).
Mold rejection reduced 100%; WTS value improved from 20–34 (70% improvement).

Net result: clear improvement in casting quality and process stability, even under trial constraints related to mixer performance — Sandiron recommended for regular production.

Proven performance. Measurable results.

We deliver solutions that drive real improvements in quality, efficiency, and productivity.
