Doctor Blades for Industrial Gravure Printing Machinery
1. Product Feature :
The ink scraping blade is manufactured by high-precision technology, and the blade is thin and flexible, with flatness and good toughness. Made of high-precision steel, the blade is highly durable, which significantly reduces production costs and saves time for frequent shutdowns or blade reshaping. Our doctor blade is made of high quality steel,the finished blade is thin,precise and has strong elasticity, good toughness and high smoothness. We adopt unique technology process and self sharpening opening design ,you don't need to turn and grind before work, which can ensure the good contact with the surface of the plate, so can achieve the best scraping effect.
