Barrels for injection moulding machines and extruders
- NITRIDED barrels – basic variant suitable for processes without the addition of glass fiber and other additives
| Inner diameter in mm | Lenght (max.) in mm | Nitrided layer depth in mm | Thickness of hardmetal layer in mm | Hardness |
| 20 ¸ 500 | 6000 | 0.5 ¸ 0.7 | - | 950 ± 80 HV |
- BIMETALLIC barrels EXTRA - suitable for processes with higher wear resistance requirements, for processing materials with glass fiber content up to 30%
| Inner diameter in mm | Lenght (max.) in mm | Nitrided layer depth in mm | Thickness of hardmetal layer in mm | Hardness |
