In a significant development for the metal manufacturing and 3D printing industries, Japanese-American startup Sun Metalon has successfully closed a $21 million Series A funding round. This latest investment marks a major milestone for the company, bringing its total capital raised to an impressive $30.7 million since its founding in 2021.

Funding Details and Investors

JIC Venture Growth Investments, HITE Hedge Asset Management, and Sumitomo Corporation Global Metals led the Series A round. Existing investors, including The University of Tokyo Edge Capital Partners (UTEC), Globis Capital Partners, D4V, i-nest capital, Scrum Ventures, and Berkeley SkyDeck, also participated in this round. Additionally, the company secured a $3.4 million loan facility from Sumitomo Mitsui Banking Corporation as part of the Series A funding.

Company Overview

Sun Metalon, a Japanese-American deep-tech startup founded in 2021, is revolutionizing metal manufacturing with its innovative “non-binder-based sinter technology.” This proprietary system uses an electromagnetic field to concentrate energy, coupled with a unique “booster material” that accelerates recycling and refining processes while enhancing energy efficiency. The technology ensures efficient and rapid heating of metal waste and fluid contaminants without melting the metal itself, potentially reducing production costs by over 90% and operating up to 500 times faster than conventional methods.

The company’s secure production platform is designed to be scalable and easily integrable into existing manufacturing environments. It boasts significant advantages in cost-effectiveness, low CO2 emissions, and space efficiency. Sun Metalon’s heating process doesn’t require fossil fuels, potentially achieving zero CO2 emissions when using clean energy sources. The technology’s modular equipment offers a higher space efficiency rate than conventional methods, making it adaptable to various industrial settings.

At the heart of Sun Metalon’s vision is the concept of “Localized Sourcing,” a hypothetical world where necessary metal components can be produced from locally available materials. This approach aims to transform the metal industry by enabling rapid metal part manufacturing, efficient metal waste recycling, and local production of metal parts. A notable application includes aluminum recycling developed in collaboration with Toyota.

Targeting automotive, construction machinery, and heavy industries, Sun Metalon’s technology significantly reduces energy consumption and CO2 emissions in metal processing. By revitalizing metal waste into reusable resources, it improves overall supply chain cost efficiency while contributing to global industrial decarbonization efforts. This innovative approach positions Sun Metalon at the forefront of sustainable manufacturing and circular economy initiatives in the metal industry.

Current Stage of Development

Sun Metalon has made significant strides in its technology development and market penetration. The company has established partnerships with leading automotive, construction machinery, heavy industry, and steel manufacturing companies, contributing to industrial decarbonization efforts across sectors. This progress is further evidenced by the expansion of their U.S. plant in spring 2024, which now serves as a hub for collaboration with American partners and as a center for metal manufacturing and recycling operations.

Simultaneously, Sun Metalon has made significant progress in intellectual property protection, with core patents granted in both Japan and the United States. These patents encompass innovations in metal purification, refining, and diffusion bonding, indicating a wide range of potential applications. The company’s active engagement with industry events and potential customers was recently demonstrated at NADCA 2024, where Sun Metalon showcased its innovative energy-efficient and cost-saving recycling technology for die casting, metal casting, and machining operations. This comprehensive approach to development, from partnerships and expansion to patent protection and industry engagement, positions Sun Metalon strongly in the evolving landscape of sustainable metal manufacturing.

Strategic Partnership with Toyota

Sun Metalon’s collaboration with Toyota Motor Corporation exemplifies the practical application of its innovative technology in large-scale manufacturing. This partnership has led to the development of a new aluminum recycling method that significantly reduces CO2 emissions. The process is already being implemented at Toyota’s Missouri plant, where it’s used in the daily production of thousands of cylinder heads, demonstrating the scalability and effectiveness of Sun Metalon’s technology.

Sun Metalon’s electromagnetic field technology has allowed Toyota to make significant strides in its circular economy initiatives, effectively avoiding the risks associated with downcycling while simultaneously improving both safety and quality in its manufacturing processes. The modular and compact nature of Sun Metalon’s equipment has proven to be a perfect fit for Toyota’s sustainability goals. By enabling on-site recycling, the technology significantly reduces the need for transportation of metal waste, further decreasing the overall environmental impact of Toyota’s operations. This alignment between Sun Metalon’s innovations and Toyota’s environmental objectives highlights the potential for tech-driven solutions in achieving industrial sustainability.

Key Team Members

Sun Metalon is led by CEO and Co-Founder Kazuhiko Nishioka, whose vision and leadership have been crucial in driving the company’s growth and innovation. The leadership team has been further strengthened by strategic high-profile appointments that bring valuable industry experience and expertise to the company. In 2023, Dr. Adrian Keppler, former CEO of EOS, joined Sun Metalon as an independent director, bringing his extensive knowledge of the additive manufacturing industry. That same year, Mark Cook, former VP of 3D Systems, was appointed as Vice President of Product and Business Development, tasked with spearheading the company’s global expansion efforts. These additions to the team not only enhance Sun Metalon’s industry credibility but also position the company favorably for future growth and market expansion.

Future Outlook

The successful Series A funding round positions Sun Metalon for significant growth and impact in the metal manufacturing and recycling sectors. CEO Kazuhiko Nishioka emphasized the importance of this milestone, stating, “This funding will accelerate our efforts to implement our heating process with client companies and expand our own metal manufacturing capabilities using local metal resources. We’re committed to driving the transition to a low-carbon, circular economy in the metal industry.”

Sun Metalon’s innovative technology is well-positioned to capitalize on the growing global metal recycling market, which the company projects will reach $52 trillion, driven by increasing environmental awareness and expanding demand. To leverage this opportunity, Sun Metalon has outlined a comprehensive growth strategy. The company plans to expand partnerships and collaborations with industry leaders, aiming to integrate its technology into more diverse manufacturing environments. Simultaneously, Sun Metalon is focusing on scaling up its own manufacturing and recycling operations to meet growing demand.

Continuous innovation remains a priority, with ongoing research and development efforts aimed at further enhancing their technology. This commitment to improvement extends to exploring new applications and markets for their metal heating solutions, potentially broadening the impact of their technology across various industries. By pursuing these interconnected strategies, Sun Metalon aims to not only grow its business but also to play a pivotal role in advancing sustainability within the global metal industry.
