Resistant and reliable, these knives are adapted to any type of polymer and extruder.
The bimetallic knife concept, invented by Amn in 1993, has brought a revolution in underwater cutting. BMS design is a major breakthrough in terms of cost and mechanical properties compared to previous monobloc titanium carbide knives.
STRUCTURE : The BMS results from the brazing of a stainless steel body with a titanium carbide (TiC) cutting edge available in 2 grades depending on the nature of die plate hard face: Nikro 128 for tungsten carbide and Nikro 143 for titanium carbide. It offers a high resistance to breakage without being detrimental to flexibility.
- BMS 1:
- Highly resistant steel body,
- Self sharpening with Nikro 128 blades.
- BMS 2:
- Same advantages as the BMS1,
- Hydrodynamic shape allows higher tip speed, reduces cavitation damage, and ensures a better pellet cooling.
| Maximum knife tip speed | BMS1 | BMS2 | |
|---|---|---|---|
| 21 meters / second | • | ||
| 27 meters / second | • | ||
