Rio Tinto has begun commissioning a major expansion of its AP60 aluminum smelter technology in Quebec, increasing primary aluminum production capacity and supporting North American supply for transportation, construction, electrical, and consumer goods markets. The project centers on aluminum smelting, a high-temperature thermal processing operation that converts alumina into primary aluminum through electrolytic reduction.
The USD$1.5 billion expansion at the Complexe Arvida facility adds 96 new AP60 smelting pots and is expected to be fully operational by the end of 2026. Once complete, the project will increase production capacity by approximately 160,00 metric tons annually, bringing total AP60 output to 220,000 metric tons of primary aluminum per year. The startup process began in March.
The AP60 technology was developed by the company’s research and development teams and, when combined with hydropower used at its Canadian operations, generates one-sixth of the greenhouse gas emissions per ton of aluminum compared with the industry average. The expansion also supports the transition to carbon-free aluminum electrolysis technology being developed through the ELYSIS partnership.
Jérôme Pécresse Chief Executive Rio Tinto Aluminium & Lithium
“For 100 years, Quebec has been at the heart of the aluminum industry, and with AP60, Rio Tinto is now strongly positioned for decades to come,” said Jérôme Pécresse, chief executive of Rio Tinto Aluminium & Lithium. He added that the expanded smelter is expected to reduce carbon emissions by up to 90% in fine particulate matter compared with the older Arvida smelter.
Rio Tinto said the AP60 expansion, together with a planned aluminum recycling center at Arvida, will more than offset production losses associated with the closure of older potrooms at the site. The project supported more than 1,500 jobs during peak construction and is expected to directly support approximately 100 permanent positions.

Strip is a critical upstream step in the production of NdFeB magnets and other high-performance permanent magnets. The process rapidly solidifies molten alloy into thin strips, forming feedstock that is further processed into high-performance magnets used in electric motors, precision actuators, and other advanced technologies. The equipment, intended for strip casting operations used in the production of rare-earth magnetic materials, is being supplied by Retech, a division of SECO/WARWICK Group focused on vacuum metallurgy and metal processing technologies.
In high-performance magnet applications, precise system atmospheric control, casting cooling rate, and thermal control during solidification directly impact downstream magnetic properties. For this reason, Retech strip casters are designed to provide stable, repeating operating conditions over sustained production cycles.
Earl Good President Retech
“Advanced magnet manufacturing depends on precision at every stage of the process,” said Earl Good, president of Retech. “Our strip casting systems are built to provide the rapid cooling rates that achieve the grain structure necessary for producing magnets that maintain superior magnetic properties, even at high temperatures. These systems will support long-term domestic supply growth.”
Retech’s strip casting platforms can be integrated into larger melt and materials handling systems, supporting continuous industrial workflows rather than isolated batch processing. The equipment supplied in this case reflects ongoing investment in domestic magnet production capacity, as manufacturers work to strengthen U.S.-based supply chains for critical materials.

Signature Vacuum Systems, a small manufacturer of vacuum furnace equipment, recently implemented an Employee Ownership Trust (EOT), placing partial ownership of the company into a trust that benefits its employees. The transition reflects a growing interest among small- to mid-sized manufacturing companies in alternatives to traditional ownership succession — particularly as many in the industry face workforce turnover and the challenge of preserving decades of accumulated knowledge.
While EOTs are still relatively new in the United States, the structure has gained traction as a way to align long-term business stability with employee engagement. For Signature, the decision was rooted in both legacy and practicality, maintaining a close-knit culture while positioning the company for future growth.
To better understand the decision and what it means moving forward, Heat TreatToday compiled key insights from the company’s announcement.
How did Signature Vacuum Systems get its start?
Co-founders Tim Horning (left) and Greg Kimble (right) | Image Credit: Signature Vacuum Systems
Signature Vacuum Systems traces its origins to a long-standing partnership between co-founders Greg Kimble and Tim Horning, who first met in 1978. The company was incorporated in 2002, with its earliest orders fulfilled out of a kitchen and a basement. Today, the company employs 15 people, and has furnaces installed as far away as Japan.
What type of vacuum furnace systems and thermal processing applications does Signature support?
Signature manufactures industrial furnaces for thermal processing applications in the metals and ceramics industries. Standard products include furnaces for processes such as brazing, sintering, and heat treating, and custom-engineered products ranging from steam-heated ovens to high-temperature ceramic sintering furnaces.

What factors influenced the decision to pursue employee ownership?
“We explored a couple of avenues with some folks that were interested in buying the company. But ultimately, we wanted to continue our legacy and keep our team employed here. We’ve developed a real family-like environment over the years, and we care about our people and their wellbeing,” says Greg Kimble.
Why is maintaining company culture an important consideration in this transition?
For smaller, specialized manufacturers, particularly in the heat treat and thermal processing space, culture and technical knowledge are closely intertwined. Maintaining that continuity can be just as important as financial outcomes, especially as experienced workers retire and industry knowledge becomes harder to replace.
What made an Employee Ownership Trust (EOT) the right fit?
“We chose the EOT structure for a couple different reasons. We liked the ease of structure of an EOT, as well as being able to modify aspects as necessary down the road. We’re also a smaller company, and the cost of an EOT was much more feasible for our size and revenue,” said Heather Bell, operations manager at Signature Vacuum Systems.
What is an EOT, and how does it function?
An Employee Ownership Trust is a structure in which a trust holds shares of a company on behalf of employees. Owners can sell stock shares to the trust and typically be paid over time. These shares then give employees some governance of the company. Eligible employees in the trust will participate in profit sharing, which enables employees to share in the company’s success. While widely used in the United Kingdom, the model is still emerging in the United States.
How might this transition affect employee engagement?
“I’m greatly looking forward to higher engagement from all our employees. They have so much to offer and valuable suggestions to give, but they didn’t always have an avenue in the past to make them heard as easily,” said Heather Bell.
How does this approach relate to broader workforce trends in manufacturing?
Ownership transitions like this are increasingly tied to industry-wide concerns about workforce retention and knowledge transfer. In technical fields like heat treating and furnace manufacturing where expertise is built over decades, models that encourage long-term employee investment can help maintain both capability and continuity.
What support was involved in executing the transition?
The company worked with Common Trust, along with advisors including JHP Advisors and the Strategic Early Warning Network (SEWN), to structure and implement the Employee Ownership Trust.
What does this transition signal for the company’s future?
The move positions Signature to grow from a place of stability, maintaining leadership continuity while creating opportunities for increased employee participation and long-term alignment.
What perspective do company leaders offer to others considering this model?
“I would suggest it to other business owners. I think it’s a great option to have,” said Greg Kimble. Heather Bell adds, “it’s well worth it. We feel that we’ve paved the way for the future of both the company and our employees.”

Andis Company, a U.S.-based manufacturer of grooming tools, has completed a controls upgrade on a vacuum heat treat furnace used for hardening components. The upgrade supports continued operation of a system critical to its production.
Andis Company finalized a PLC system overhaul on its ECM FLEX vacuum furnace, transitioning from an aging S7-300 processor and Profibus network to a newer S7-1500 series processor with Profinet communication. The upgrade also included remote input/output integration across the system. ECM USA supported the project planning and on-site execution, with the work completed on schedule and with minimal disruption to production.
The three-cell hardening modular furnace operates at approximately 950°C (1724°F) and includes a 20-bar gas quench, along with loading/unloading automation. Installed roughly 15 years ago to replace molten salt baths, the system supports clean heat treatment to avoid part discoloration and reduce the need for post-heat treat cleaning. The furnace remains central to Andis’s Wisconsin operations.
Tom Hoffelder Director of Manufacturing Support and Innovation Andis Company
The upgrade was initiated in 2025 following end-of-support announcements for legacy controls. “In 2025, we determined that we needed to fully replace the CPUs in our ECM vacuum heat treat system after Siemens announced end-of-support for significant portions of the controls,” said Tom Hoffelder, director of manufacturing support and innovation at Andis Company. “Because reliable day-to-day operation of our heat treat system is critical to our business, we worked closely [with ECM] to define the project scope and map out the execution plan.”
The project focused on modernizing hardware, improving long-term reliability, and maintaining throughput during installation. The updated controls and HMI remained familiar to operators, allowing the system to return to full production without additional training, Hoffelder added.

The PGA platform aims to address these requirements through controlled processing and scalable parameters.
The system will contribute to strengthening domestic supply chains and reinforcing U.S. technical capabilities in critical materials.
Earl Good President Retech Source: Retech
“National labs are focused not only on proving what’s possible, but on proving what’s practical,” said Earl Good, president of Retech. The PGA platform enables movement from controlled pilot-scale experimentation to production-scale capability. Its design allows processes to be scaled once validated, without requiring significant redesign, he added.
Beyond individual equipment capabilities, the platform is designed for integration with existing lab infrastructure, allowing coordination across operations, maintenance, and training. This enhances cost efficiency while maintaining performance standards.
As demand grows for domestic production of critical materials, the company continues to develop scalable solutions aimed at strengthening supply chains and materials innovation.

The furnace joining Treatnorte’s machine park is a medium size system from SECO/WARWICK, a global manufacturer of heat treatment equipment with operations in North America. It is configured to provide a broad process range and production flexibility.
The round heating chamber allows processing of relatively large parts, while the combination of high-pressure gas quenching (HPGQ) up to 15 bar abs, combined with dedicated low-pressure carburizing (LPC) technology, enables complete process cycles for a range of steels used by Treatnorte’s clients. The furnace provides temperature uniformity, convection heating at lower temperatures, and directional cooling, supporting control of quenching processes for complex geometries.
The furnace configuration also incorporates FineCarb technology, SECO/WARWICK’s low-pressure carburizing solution carried out in a vacuum atmosphere, where carbon introduction is precisely controlled through successive pulses of carbon-bearing gases. This process allows for uniform and repeatable carburized layers with minimal part distortion and reduced cycle time.
The equipment will serve both the Portuguese and Spanish markets, where it will support ongoing tool steel heat-treatment operations. “The ability to independently perform vacuum hardening and carburizing processes significantly increases operations independence, shortens the supply chain, and allows for better quality control. FineCarb technology, combined with 15-bar gas quenching opens up opportunities for Treatnorte to win more demanding projects for [clients] in Portugal and Spain,” said Nuno Carvalho from Treatnorte.

Initial production plans called for four separate units — an oil quenching furnace, tempering furnace, cryogenic unit, and washing system. Following a joint technological analysis, SECO/WARWICK, a global manufacturer of industrial furnaces with operations in North America, demonstrated that these processes could be performed within a single vacuum furnace with gas quenching. Trials confirmed the approach met the client’s requirements while simplifying the overall process.
The system is a horizontal Vector vacuum furnace designed to support multiple heat treating operations in one unit. It features a round heating chamber with temperature uniformity of approximately 5°C (9°F), a convection heating system for improved low-temperature efficiency, and a vacuum pumping system combining mechanical and Roots pump for stable operation.
Additional capabilities include partial pressure control system to limit alloy element evaporation and a 15-bar gas quenching system with inverter controlled to stabilize cooling and reduce power demand peaks. The furnace also supports vacuum carburizing (FineCarb), pre-nitriding (PreNitLPC), low-pressure carbonitriding (LPCN), and deep cryogenic treatment down to −80°C (−112°F) within an automated cycle.
By consolidating these processes, the system is expected to improve repeatability and production efficiency, while eliminating the need for post-quench oil cleaning.
Maciej Korecki Vice President of Vacuum Business Segment SECO/WARWICK
“Initially, several separate devices were considered, each handling subsequent stages of the process. After analysis and technological testing, it turned out that all these operations can be carried out in a single vacuum furnace with gas quenching. This means not only substantial investment savings but also simplified production, shorter process times, and reduced labor requirements. For the [client], it is also the first step toward modern vacuum processes and moving away from the atmospheric technologies previously used,” said Maciej Korecki, vice president of the Vacuum Segment at SECO/WARWICK.
