Description

When using water-based ink print patterns, rust becomes a larger risk for doctor blades. To prevent that, the SL-45 stainless steel doctor blade is made of a German 4037YR stainless steel for a better corrosion resistance.

Compared with SL-35 blade, the SL-45 doctor blade has a higher hardness, which makes it suitable for a variety of ink types. Due to its excellent durability, the SL-45stainless steel doctor blade is also more suitable for cylinders and inks that tend to accelerate blade wear.

Advantages
  • A heat treatment process prevents wear and oxidation of the blade edge.
  • Less granules resulting from blade wear at a printing speed of 250m/minute reduces ink pollution levels.
  • The polishing process ensures the blade surface is smooth, thus preventing ink impurities from sticking to the blade. This ensures the blade continues to maintain an excellent removal effect during high speed printing.
  • Compared to a standard doctor blade, the SL-45 is made of a high grade stainless steel with a better oxidation and corrosion resistance, as well as a longer service life.
