Harper International (Lancaster, N.Y.) has launched its next generation of custom oxidation ovens for processing carbon fiber. Available at 300-mm/11.8-inch to greater than 4,000-mm/157.5-inch tow band widths, the ovens feature the company’s proprietary atmospheric seals, which reduce fugitive emissions, increase the active volume of the oven, and offer reduced energy consumption, compared to previous and competing systems. According to the company, the ovens’ modular-construction design reduced field installation labor by 90 percent, when an oven was recently incorporated into a full-line (300-mm/11.8-inch) pilot system. Company-guaranteed benefits include faster oxidation, improved velocity uniformity and velocity range capability, assurance of temperature uniformity throughout a variety of flow rates, and optimal control of the carbonization reaction to ensure fiber quality.
