Our carbide nozzles are made of tungsten carbide material with a hardness of up to HRA90 and above, and bending resistance of up to 2300N/mm. They have an excellent balance between wear resistance and being too brittle.

Each nozzle is made of a solid piece of material with no joints, to ensure a smooth path for wire travel. The inner bore is ground and polished to Ra0.1. Both the inlet and outlet radii have been scientifically calculated and processed to a surface finish of Ra0.025, ensuring smooth travel and minimal wire stress during winding.

Concentricity between the clamping diameter and outlet diameter is 0.01mm. The inner more diameter’s tolerance is 0.01mm. It is excellent for precision coil layering.
