We take on a comprehensive view of issues pertaining to material transport that extend beyond individual unit operations. Our expertise designing material handling, raw material through product packaging, ensures best functionality, maximizes throughput, minimizes scrap and maintains consistent product quality. Harper offers a variety of feeding and material handling solutions, including creel stations, winders, drive stands, and material conditioning such as combs, moistener, spreader bars, bypass rollers, and centering roll systems.
Pre & Post Treatment and Material Conditioning
Harper engineers bring a wealth of experience in pre and post-treatment and material conditioning using a variety of solutions. Whether traditional or emerging methods – chemical, electrochemical, plasma, or gaseous treatments – we work with your process to ensure thoughtful management of chemical preparation and minimization and treatment of the effluent solutions from the conditioning.
As the standard in thermal processing technology for carbon fiber since the industry’s inception, Harper offers a range of equipment in thermal regimes beyond what others can, including furnaces and oxidation ovens in lab scale, pilot scale and full production scale sizes. We have the building blocks to design solutions for the most challenging thermal processes, using our years of experience and practice to devising first-of-a-kind, custom systems for world class material manufacturers.
Gas Treatment and Handling
Harper approaches gas treatment and handling with several objectives. Not only do our designs focus on managing emissions and treatment of off-gas in an environmentally conscience manner, but we also carefully consider opportunities for energy recovery for use within the process.

Fully Integrated Control Systems
From first point of engagement, Harper carefully designs a production plant with rigorous detail and thoughtful consideration of how the facility will be operated. Our controls group develops sequence of operations (SOP’s) that drive simultaneously toward efficiency, and enhanced product quality. Our fully integrated systems connect all process equipment to one centralized control system, ensuring operation is that of a cooperative plant all functioning on the same control platform rather than individual and isolated control platforms.
