A Swedish Ductile Iron foundry and a Danish aluminum shop may both source molten metal filtration from the same European suppliers, but their specification sheets rarely match. Pore count, material chemistry, EN compliance documentation, and preferred filter geometry...
Every foundry engineer has seen a filter fail mid-pour, letting inclusions creep into the casting and scrapping a batch that should have shipped. When you're running high-temperature alloys or special steel, the culprit is often simpler than it looks. Your ceramic...
Every foundry engineer knows the frustration of looking at two refractory materials with nearly identical chemistry, only to find that one insulates twice as well as the other. That performance gap rarely comes down to the base ceramic. It comes down to trapped air:...
