A century-old U.S. company has received orders from multiple Chinese firms for carbon-fiber ovens.

Despatch Industries, Minneapolis, will build the production-scale oxidation ovens with center-to-ends airflow and new atmosphere control and energy reduction technology that it calls ACER.
"As the carbon-fiber market is growing and becoming more active in China, we are seeing a strong increase in interest from Chinese manufacturers," says Ken Defiel, global carbon-fiber sales manager.

Oxidation is a critical step in the production of carbon fiber. Despatch says its center-to-ends airflow design creates consistent process conditions with uniform temperatures in the working zones for uniform, oxidized density fiber and higher yields by as much as 30 percent.

According to Despatch, ACER is a management system that reduces energy consumption and tar contamination, while improving fiber quality.
