Intelligent systems powered by advanced analytics for precision sand control in green sand foundries unassisted

Casting rejections, even though sand parameters are maintained well within their control ranges, is one of the biggest challenges foundries are facing today. Multiple sand parameters are measured in a foundry regularly. All these parameters are analyzed and monitored with a basic assumption of them being independent of the rest of the parameters.

Optimizing green sand castings with Nanotechnology

Coarse grained sand permits metal penetration into molds resulting in poor surface finish. Fine grained sand on the other hand yields superior surface finish but needs a higher binder content. This means increased sand sticking and hence increased shot-blasting time.

Nanotechnology for better surface finish in Green Sand foundry

The only role of carbon in Green Sand is to form a non-wetting barrier between the molten metal and sand. This is a case study of how our nanotechnology based carbon additive helped save ₹2,00,00,000 per year and reduced CO2 emission by around 3,00,000kg per year
