Controlled Fusion Equipment

Forging the skeleton of an artificial sun

Huali Energy manufactures the vacuum vessels, thermal shields, coil cases, and cryostats at the heart of fusion reactors, taking part in national and international fusion programs including ITER, CRAFT, and BEST through its core equipment.

Core Component Manufacturing for Extreme Tokamak Temperature Zones

To contain a sun at temperatures near absolute zero: the vacuum vessel surrounds the plasma, the thermal shield blocks radiant heat, the coil cases withstand immense magnetic forces, and the cryostat seals the system in vacuum, bringing stellar heat into a room-temperature engineering boundary.

Manufacturing Strength

Fusion reactor core components are difficult to manufacture because they must be large, cryogenic, vacuum-tight, and delivered as complete systems — Huali Energy supports system-level delivery with four core capabilities.

Large-Scale Fabrication

12 × 18 m

Manufactured the world's largest TF magnet coil case, with the capability to form, weld, and assemble giant reactor core components.

Cryogenic Service

-269°C

Built for superconducting magnets near absolute zero, ensuring structural reliability under extreme low temperatures.

Ultra-High Vacuum

Vacuum Sealing

Manufactured vacuum vessels and cryostats that meet the high-vacuum and long-term sealing demands of fusion devices.

System-Level Delivery

Full Coverage

Integrated delivery of all four reactor core components — vacuum vessel, thermal shield, coil case, cryostat.
