Why Slag Inclusion Occurs in Ductile Iron and How Foundries Can Stop It
In today’s competitive casting industry, delivering high-quality ductile iron components is no longer optional—it is essential. Automotive, infrastructure, machinery, and engineering clients expect castings that meet strict dimensional, mechanical, and surface standards. Even minor defects can lead to rejection, rework, delayed shipments, and damaged business relationships. One of the most common and costly defects in ductile iron production is slag inclusion. These non-metallic impurities trapped inside castings weaken the structure, reduce performance, and increase scrap rates. For foundries focused on long-term growth and customer satisfaction, Eliminating Slag Inclusion Defects Of Ductile Iron Castings must be a top priority. In this article, we explain why slag inclusion occurs, how it affects casting quality, and what practical steps foundries can take to prevent it. We also share proven industry practices followed by experienced suppliers like Bansal Brothers to ensure clean an...
