GRAVURE ROLL
NEW EXPERIMENT SOLUTION TECHNOLOGY
Carbon Roll
Carbon Guide Roll (Patent No. 10-1253727)
Carbon guide roll boasts outstanding elasticity and strength thanks to the ultra-light carbon material and ensures light weight, high strength, and high-risk rotation numbers. Mainly used for surface finishing of liquid crystal, film, printing, and paper, it prevents creases and reduces defect rate, thereby, improving product quality.
