In the transition to Foundry 4.0, eliminating the operator-dependent Zahn flow cup is critical for reducing scrap and boosting Overall Equipment

From Manual Sampling to Real-Time Slurry Control

In the transition to Foundry 4.0, eliminating the operator-dependent Zahn flow cup is critical for reducing scrap and boosting Overall Equipment Effectiveness (OEE). SlurrySense provides continuous, inline viscosity and density measurement of the ceramic dip-coat slurry. Its self-cleaning, solid-state design maintains tight rheological control even in abrasive, fouling fluids, preventing defects like cracking and surface erosion. By enabling closed-loop automation of binders and diluents, it ensures consistent shell thickness and strength across every shift without the intermittent lag of manual sampling.
