SELF-SHARPENING
Self-sharpening scraper blades
Sandsteel operates in the flexography and rotogravure segments, providing imported self-sharpening blades for packaging, labels, and tags.
Our suppliers are ISO certified and guarantee blades of the highest quality for ink application, scraping, and dosage during the printing process.
The self-sharpening scraper blades are manufactured with imported fine microstructure steel specially developed for the flexographic (conventional and encapsulated Doctor Blade system) and the rotogravure printing processes, ensuring better definition for lines, reticules, and solid printing, in addition to allowing for a long lifespan of the production process.
These blades have an undercut recess in one of their extremities, which goes attached to the printer in contact with the anilox cylinder, scraping and dosing the ink that is transferred to the blanket and, later on, to the employed substrate.
The steel used to manufacture Self-sharpening Scraper Blades is of utmost importance. Thus, the raw material employed in its production is essential to guarantee printing quality.
