Chrome Rollers
Hardness of our Chrome Rollers is super hard, 72rc as deposited. Only the diamond is harder than chromium. SPAN Chrome’s high hardness value makes it abrasion and corrosion resistant. It is essential that Chrome be applied to a base metal which is hard enough to give it the necessary support.
SPAN Chrome Rollers have the lowest coefficient of friction. Its low coefficient of friction means less drag and therefore, less heat is generated as the parts rub together. Our Corrosion Resistance Chrome resists attack by most organic and inorganic compounds except sulfuric acids, to gain the greatest advantage of this property. Our Chrome deposited surfaces will be continuous and free from pin holes and other imperfections. Surfaces with good corrosion resistant properties will exhibit less chemical attack with no generation of metallic oxidation products which become abrasive particles damaging the base metal Heat Resistance.
Rilsan Rollers
We are specialised in the manufacturing of Rilsan Rollers and to achieve the best possible surface for Rilsan-Rollers, specialised, ultra-modern surface machining equipment is available.
Produced to the highest standards, Rilsan Rollers offer the following: Excellent quality surface finish which leads to easy cleaning, Good impact resistance, Long service life, Very good chemical resistance, Low friction surface.
We recommend Rilsan because it has excellent resistance to the chemical influences of printing ink. The absorption of water and ink is very low and the surface is very smooth and durable. Rilsan replaces copper, or ebonite in ink vibrator rider positions in lithographic and letterpress systems. Rilsan is suitable as ink transfer roller and ink metering roller.
