Steel Coating Doctor Blade

As a high-grade printing products, coated paper and paperboard should not only have good printable performance, but also put forward quite high requirements for the delicacy of printed matter, that is, coated paper and paperboard must ensure the printable performance and use requirements of clear, full, fresh cesium, bright and uniform.As an important part of the coating machine, the quality of the coat doctor blade directly affects the quality and production efficiency of the coated paper.

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.
