📢 Casting defects draining your foundry's profitability?
Slag inclusions, sand holes, trapped gases — every defective casting means wasted material, rework costs, and lost revenue. For years, foundries have struggled with inconsistent filtration that simply can't keep up with demanding quality standards.
Here's the solution that actually works.
SEFU CERAMIC Silicon Carbide Foam Filters are designed specifically for ductile iron, grey iron, and non-ferrous alloy castings, with exceptional resistance to attack and corrosion from molten iron liquid. The three-dimensional interconnected mesh structure achieves a porosity of 80%-90%, effectively capturing oxides, non-metallic inclusions, and slag while providing stable laminar flow to prevent turbulence. The result? Significantly reduced defect rates, improved mechanical properties, and lower rejection rates across your production line.
