Wear protection linings for extrusion or injection moulding cylinders
SSiC, Si3N4 and Al2O3
- high wear resistance due to high strength and hardness
- high chemical corrosion resistance
- low density, i.e. small mass moment of inertia
- no metallic contamination
Compared to metallic linings, ceramic linings provide both higher wear resistance and lower adhesion of the extrusion media.
