Summary
In Gold Nugget 48, we welcome Chris Sleath and Scott Meyer from Spartan Light Metals Inc., who sponsored this episode. Spartan is a U.S.-based die caster that’s making serious waves with its investment in Rheocasting technology. Spartan was the first company in the USA to implement the Comptech slurry maker, and over the past two years, they’ve shifted from being a traditional powertrain supplier to an R&D-driven structural casting innovator. Together with hosts Fabian Niklas and Staffan Zetterström, Chris and Scott share what it takes to introduce new processes, rethink old assumptions, and bring advanced aluminium solutions to market in a highly competitive space. Key Takeaways: * Spartan is leading Rheocasting in the U.S. Spartan Light Metals is the first company in the United States to install and run a Comptech slurry maker. They’re not just testing Rheocasting, they’re scaling it. * From powertrain to structural castings Traditionally focused on drivetrain housings, Spartan is now moving aggressively into structural parts. Their R&D efforts are focused on helping OEMs design lighter, stronger components for next-generation EV platforms. * It’s not just about tech—it’s about approach Instead of chasing headlines, Spartan is taking a methodical, engineering-first route. By modifying existing HPDC tools and integrating Rheocasting without disrupting production, they’re showing how to do it the right way. * More die life, less porosity, better parts Customers are already seeing the benefits: longer die life, improved flow lengths, and cleaner parts with less gas entrapment. Rheocasting is proving itself on the shop floor, not just in PowerPoints. * Global partnerships for a global footprint Through a new alliance with KS Huayu Alutech, Spartan can now support…
