Key Takeaway In green sand foundry practice, the sand system itself is not premixed — rather, a premix additive package consisting of bentonite(s), seacoal, and auxiliary materials is added to the system sand during mulling. Engineered premix formulations from HWI simplify additions, tighten process control, and deliver consistent metallurgical performance across iron and steel casting…

Every casting starts the same way, with foundry ladles. Whether it is iron at 2,600°F, steel at 3,200°F, or aluminum at 1,300°F, someone or something has to safely pick up that liquid metal and put it exactly where it needs to go. That job falls to the ladle, one of the most underappreciated pieces of…

Accurate foundry temperature measurement is the backbone of consistent metal quality. Whether you’re tapping a cupola, treating a ladle, or pouring investment castings, knowing the exact temperature of molten metal in real time determines everything from mechanical properties to yield. For decades, foundries and steel mills have relied on Heraeus Electro-Nite, “HEN” for immersion thermocouples…
