1DEKEJIE can customize doctor blades with whichever type of edge you want. Doctor blade edges are divided into three categories, beveled edge, lamella edge and rounded edge.
Lamella doctor blade
The lamella edge ensures that the thickness of edge remains unchanged. Within the lifespan of blades, doctor blades with a lamella edge can perfectly and quickly make contact with the cylinder roller the moment the printing press begins operation. The doctor blade with lamella edge minimizes waste.
The edge of common, middle end and high end coating doctor blades is standard.
Carbon steel doctor blade with lamella edge: The blade is made of carbon steel and coated with a special coating that minimizes the wear of the doctor blade resulting from pigment particles, which prevents the appearance of ink streaks and the change of print color. Our common coating doctor blade can be used in the coating process.
Special coating doctor blade: The hardness material coating of the blade edge extends the lifespan of the blade, reducing the change time of the doctor blade, protecting the cladding of the anilox roll and pattern. Besides, middle end and high end coating doctor blades effectively remove excess ink better and prevent the appearance of ink streaks. The special coating doctor blade can even be used to remove excess UV ink.
Beveled doctor blade
Doctor blades with a beveled edge with a bevel angle from 4 to 15 degrees have great elasticity and maintain blade contact with the cylinder at a suitable angle. Beveled edges with larger angles can reduce the wear of the blade and break the frequency of the blade. The smaller the contact area, the better effectiveness in removing ink. So beveled doctor blades with higher hardness and better durability are more popular.
Doctor blade with rounded edge
Doctor blade with rounded edge is classified by the radius. The blade with large radius is usually used to print large-area pattern on textile. And the blade with small radius is usually used to print product with low accuracy by using ink with low viscidity.
Doctor blade with 3 degree bevel edge
The edge with 3 degree angles ensures the stability of the doctor blade, minimizing the bending of the blade under excessive blade pressure and hazing.
