Coated paper and cardboard as one of the main materials of printing and packaging, its users have higher and higher requirements for quality, exquisite paper surface, stable quality.The coated scraper plays a very important role.

• High carbon steel coat doctor blade:traditional wrinkle doctor blade with tempered
• Ceramic coat doctor blade: suitable for high speed coating machine, choose import steel as the base material, use thermal spraying technology to spray ceramic coating on the blade edge surface. It have good wear – resistant, service life is 5~6 times that of traditional steel coat doctor blade.High manufacturing precision, can improve the fineness of paper, can run for a long time, improve the capacity.
• Tungsten carbide coat doctor blade:imported steel coated scraper combined with thermal spraying technology, in the blade spraying tungsten carbide coating, and then grinding processing.It has good wear resistance, long service life, high manufacturing accuracy and smooth surface, which can reduce the roughness of paper surface and improve the stability of paper quality.
