01 – Our Casting Heritage

Five Decades of GettingThere First.

Founded in 1984 on Bill Coors’ vision that recycled aluminum could be continuously cast into high-quality sheet, efficiently and at scale. Today, we continue that legacy.

From Lauener to Nexcast®1984 → 2025
  1. 1984

    Golden Aluminum founded. Original Lauener blockcaster commissioned in Fort Lupton.

  2. 1987

    Golden acquires Lauener's blockcasting technology.

  3. 2012

    Infinity Alloy Series launched. AA5016 made from 75%+ recycled cans.

  4. 2016

    Partnership with SMS group begins. Nexcast® development starts.

  5. 2024

    $22.3M DOE grant awarded for industrial decarbonization.

  6. 2025

    Nexcast® goes into commercial operation.

02 – The Install

What It Takes toReplace a Caster.

The original plan called for five weeks. Getting there meant fully decommissioning and removing the old caster. Months of prep work brought it in ahead of schedule.

03 – The Technology

The Most Advanced Casterin Operation.

Nexcast® isn’t just an upgrade for Golden Aluminum — it’s a step forward for the entire flat-rolled aluminum industry. Here’s what sets it apart.

01

Compact By Design

Nexcast® runs molten metal to finished coil on one consolidated line, with no ingot casting, no reheat furnaces, and no storage in between.

02

Intelligent Process Controls

Operations that once took a person now run themselves. Controls adjust in real time.

03

Proven In Production

Nexcast® is capable of running extended continuous casting campaigns and switching between a wide diversity of alloys without stopping.

04

Moving Copper Mold Design

A proprietary moving mold casts high-alloy and heat-treatable grades, including AA5182, that conventional continuous casters can’t.

05

Higher Recycled Content

Rapid solidification takes more scrap than DC casting can handle. More than 80% recycled content, depending on alloy.

06

Built For Continuity

Campaigns designed for fewer stops, fewer consumables, and a caster built to run for the next 50 years. Continuous casting efficiency with direct casting quality.

05 – Sustainability By Design

Efficiency Isn't an Add-On.It's the Architecture.

Every design decision started with resource efficiency like the compact footprint, the elimination of intermediate steps and the tolerance for high scrap content.

This isn’t new for Golden. The mill was built in 1984 around a single premise: that recycled cans could be cast into new sheet using a fraction of the energy.

Sustainability isn’t a strategy we adopted. It’s the reason we exist.

06 – Our People

“All the technology that goes into the new machine is inherently safer. Less interaction with the machine keeps people safer.”

Jeff Frim — Jeff Frim, President & CEO

Built for the PeopleWho Run It.

A new operator pulpit puts the full process in view. Automated controls handle most of what used to be done by hand. Every change makes this caster safer for operators.
