Filter Blades for Plastic and Rubber Manufacturers

At Fernite, we manufacturer Filter Blades that cut, scrape, or shear plastic residue from filter screens, rotating drums, or die faces. To fit various OEM machine specifications these blades can be manufactured in different dimensions.

We manufacture Filter blades from D2 tool steel, HSS, and tungsten carbide.

D2 Tool Steel is often used for general applications. This steel provides a good wear resistance.
Tungsten Carbide-Tipped Steel is used for extremely hard plastics and high-abrasion environments.
High-Speed Steel is used for precision applications requiring fine cuts.

Also, various coatings can be applied to protect blades from wear and corrosion: dTiN, CrN, or PVD.

On customer request we can manufacture Filter Blades with different edges:
Straight, Serrated, Scalloped or Beveled.

To Order the Correct Filter Blades:

Match the blade to your machine rotation/feed direction
Blade Coatings: Use TiN, CrN, or DLC coatings for reduced friction and extended lifespan
Check OEM part numbers or orientation markings
Use matched pairs if the machine uses both left- and right-handed blades
Select material and coating based on what you are cutting (some materials are more abrasive)
Underwater vs. air-cooled pelletizing may need different edge geometries
Precision & Flatness: Vital to avoid pressure points or melting inconsistencies
