Proprietary Process & Planet‑Positive Performance

Sun Metalon’s breakthrough comes from its Venus‑L6 “oven‑sized” modular unit, which uses electromagnetic induction and a heating booster to heat and clean contaminated swarf, chips and sludge, without melting the metal. By heating at the boiling point of oil, the machine evaporates machining fluids and condenses them as waste, then recovers dry briquettes at up to 90% purity, ready for reuse.

This compact system, about the size of an industrial oven, can be placed directly on the shop floor, eliminating transportation and landfill costs, and operates on-site with zero CO₂ emissions when powered by renewables.

Efficiency Enhancements & Emission Eliminations

Compared to traditional gas‑fired furnaces, Sun Metalon’s heating technology cuts energy consumption by ~85% and lowers processing cost by ~10%. The process recovers metal that would otherwise be lost, up to 20% of input by weight, turning waste into high‑value briquettes worth 9× more than low‑grade scrap.

Patent‑Protected & Pilot‑Ready Platform

In 2024, Sun Metalon secured two domestic patents in Japan and the US for its inductive heating and boosting technology. The Venus‑L6 has completed commercial pilots in Japan and the US, and the company is expanding production-ready units for automotive and foundry sites.

Strategic Investors & Synergistic Strength

The $9.1 million Series A round includes Nippon Steel, JBIC, Airbus Ventures, and Shimadzu Future Innovation Fund. Nippon Steel offers industrial scale expertise; Shimadzu brings analytical tools to validate metal composition; Airbus adds aerospace domain insight; JBIC provides green‑tech finance .

Commercial Adoption & Circular Economics

Sun Metalon units are being trialed across automotive OEMs, foundries, steel mills, and saw early adoption by Toyota for aluminum recycling. By recycling contaminated swarf on‑site and recovering up to 90% melt yield, the system creates direct circularity, cuts logistics, and offers at least 40% lower OPEX 

Future Pathways & Scale‑Up Strategy

Sun Metalon plans to launch its first industrial-scale units by late 2026, powering them through funds towards pilot installations, workforce expansion and production scaling . The company aims for broad deployment in automotive, aerospace, and steel-plants to reshape metal supply chains.

Environmental Impacts & Industrial Implications

By enabling modular, zero‑CO₂ recycling, Sun Metalon offers a solution addressing ~7% of global CO₂ from steel/aluminum production. Its decentralized model also reduces landfill volume and cross-border swarf logistics, supporting a circular‑economy paradigm.

Key Takeaways

• Sun Metalon’s Venus‑L6 unit uses inductive heating & boosters to recycle swarf into metal briquettes with zero CO₂ emissions and 85% less energy use.

• The process recovers up to 90% purity metal, delivering 9× more value than low‑grade scrap, with 10% cost savings in recycling

• With $39.8 million total funding, including $9.1M in Series A, the company is scaling operations in the US and Japan, targeting industrial rollouts by 2026.
