About Hansa Oberflächentechnik Werner
Hansa Oberflächentechnik Werner is a company specialized in the refurbishment of worn metal rollers based in Osterholz-Scharmbeck. The company repairs and coats all types of rollers and applies protective and functional layers. Methods include flame spraying, the electric arc process, as well as High-Velocity Oxygen Fuel Spray (HVOF); highly resistant anti-corrosion layers are also applied. A focus is placed on on-site processing at the customer's location: dry cylinders and carrier drums in the paper industry, as well as calendering rollers, are ground in place—in all diameters and sizes, cylindrical or contoured, including contour measurement protocols. The company deepens or widens existing Chevron gears and Venta-Nips as required, restores worn rollers, and brings 4-roll calendering rollers back to specified dimensions, contour, and roughness. Customers include the paper, tire, and sealing industries, food production, as well as flooring and film manufacturing.
