Using high-quality steel for doctor blades is essential for achieving precision, durability, and consistent performance in demanding printing and coating applications. At Fuji Shoko, we are dedicated to using only steel that meets the highest standards of straightness and flatness to ensure optimal blade performance. Backed by over 40 years of research and development, our proprietary metal processing techniques significantly reduce impurities, producing a cleaner, more stable material. This refined process also promotes the formation of nano-structures within the steel, which enhances uniform blade wear and extends durability over time. As a result, our doctor blades offer superior resistance to wear, abrasion, and corrosion—leading to longer service life, fewer replacements, and reduced maintenance costs.
Our proprietary surface grinding methods allow us to achieve high-precision blade edges and shapes. By applying high-precision processing technology, we ensure smooth initial printing performance and optimal blade functionality throughout. The blade edge of the doctor blade is treated with the utmost care and undergoes rigorous inspection to maintain the highest quality standards. As a cost efficient option, we offer double-edge blades and provide custom edge-angle processing tailored to specific printing needs.
Our advanced coating technologies enhance wear and tear resistance, reducing the frequency of blade replacements and improving overall operational efficiency as well as reducing cost. Applying newly developed surface treatments significantly enhance their performance, longevity, and consistency in high-speed, high-precision printing and coating environments, while minimizing common doctoring issues such as streaks, arrow marks, feathering, and blurring. Coated blades also experience less edge wear, helping to reduce burrs and maintain high print quality. Additionally, our coatings provide anti-rust protection and are fully compatible with water-based printing inks.
