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 castingsTraditionally 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 approachInstead 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 partsCustomers 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 footprintThrough a new alliance with KS Huayu Alutech, Spartan can now support programs across North America, Europe, and Asia. One design, one partner, global delivery.

* Sustainability with a business caseRheocasting uses less energy and generates less scrap. Spartan is pushing toward carbon goals not because of regulation, but because it makes economic sense.

Technology leadership, not just slogans.

What emerges from this conversation is a clear picture of a company that knows who it is and where it’s going. With a deep commitment to engineering, Spartan is building a bridge between legacy know-how and next-generation manufacturing, with Rheocasting as a central pillar.

And yes, they’ll be at Euroguss 2026 in Nuremberg. If you’re curious about Rheocasting, structural die casting, or just want to meet the people behind the "space trumpet," make sure to stop by their booth; Saint Kevin (and a cold beer) will be waiting.

Thank you for listening. We’ll see you in the next episode, where we’ll continue to bring you the latest insights and updates from the casting world. Don’t forget to ask questions, write comments, or make suggestions for future episodes. Until next time, keep casting strong!
