The commercial-scale Harper carbonization line, a turnkey thermal processing solution for carbon fiber manufacturing, is scheduled for shipment to Fujian Fuwei’s site in Yong’an City, Fujian province in February 2026. Harper’s custom engineered carbonization line will comprise 3-meter-wide oxidation ovens, low- and high-temperature furnace systems, waste gas abatement systems, surface treatment systems and integrated additional unit operations, controls and services.

For Fujian, Harper’s technology advancements equal optimized fiber quality due to rapid oxidation, improved velocity uniformity, assured temperature uniformity and optimal control of the reaction. These advancements combined with Harper’s on-site services for installation and startup support, enables efficient transition to commercial production rates.

This equipment contract is a critical element in this first phase of the Fuwei high-end new material project investment valued at 2.3 billion yuan ($320 million) which aims to achieve an effective annual production capacity of 4,000 metric tons of carbon fiber per year. After this first phase, the long-term project plan is to use 1,142 acres of land with an overall planned production capacity of 50,000 metric tons per year.

“Harper’s carbonization lines continue to be the preferred choice for both advanced fiber producers and new market entrants who look to minimize their risk and timeline to commercialization,” notes Paul Elwell, vice president of Harper International Corp.
