Carbide Coil Winding Nozzles

These nozzles are made of a solid piece of high grade super hard material. There are no joints, so as to ensure smooth path for wire travel. With a material hardness of 90HRA, it possesses an excellent balance between its wear resistance & being brittle. We select the tungsten alloy to manufacture the nozzles by precise polishing ends and hole inside. This material has a hardness over HRA900 and it also has been processed special lapping. In each process step, we use the latest inspection machine to ensure the wire's insu|ating |ayer not be suffered by any damage.
Advantages :

• Precision : Concentricity between the clamping diameter and the outlet diameter is 0.01mm. Inner bore diameter’s tolerance is 0.01mm. Our precision wire guide nozzles are excellent for precise coil layering.
• Minimum friction : Every inner bore is fully polished. Both inlet and outlet radius are carefully calculated, shaped and polished to mirrored finish to eliminate scratching of the enamelled layer of wire.
• Extensive range : With over 3,000 types of carbide wire guide nozzles in our database, we keep stock for most of the common sizes in our inventory.

• High impact resistance

• High rigidity

• High hardness

For special shapes and custom sizes such as motor nozzles, we can usually produce and ship within a week.
We can also produce small quantities based on customers’ requirements.

TROPHY'S carbide nozzles W series is made of tungsten carbide material. with a hardness up to HRA90 and above, and bending resistance up to 2300N/mm. It has an excellent balance between the wear resistance and being too brittle. Each nozzle is made of a solid piece of material with no joints so as to ensure a smooth path for wire travel. The inner bore is ground and polished to Ra0.1. Both the inlet and outlet radii are scientifically calculated and processed to a surface finish of Ra0.025 ensuring smooth travelling and minimal stress to the wire during winding.

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