Tungsten Carbide Guide Nozzle Parts

Tungsten Carbide Guide Nozzle Parts, also known as tungsten carbide wire nozzles or tungsten carbide guide pins, are precision guiding components made from the superior properties of tungsten carbide. Their core function is to guide wire smoothly through the wire, preventing damage. They are key components ensuring production precision in various industries such as winding and wire drawing.

Product Material

Tungsten Carbide Guide Nozzle Parts are primarily made of high-quality tungsten carbide (tungsten steel). Some products are used in combination with auxiliary structures such as steel bases. Different grades of tungsten steel are suitable for different applications. For example, YG6X grade combines good wear resistance and toughness, making it suitable for guiding steel wire and non-ferrous metal wire; YG8 grade has excellent overall performance and can handle most conventional wire processing scenarios.

Product Performance

Tungsten Carbide Guide Nozzle Parts generally achieve a hardness of HRA90 or higher, with a bending strength reaching up to 2300 N/mm². Their wear resistance far exceeds that of ordinary steel, and their service life is more than 10 times that of similar steel parts. They maintain high hardness even at 550℃ and have a low coefficient of thermal expansion, ensuring structural stability in production environments with alternating high and low temperatures. After special processing, they possess certain corrosion and oxidation resistance, making them suitable for various industrial environments.

Structural Design

Tungsten Carbide Guide Nozzle Parts are mostly designed with a tubular structure, divided into a clamping section and a lead-out section. The clamping section has a slightly larger outer diameter to ensure stable installation, while the lead-out section has a hole diameter designed to match the wire specifications, with a smooth transition between the two. The inner hole and the inlet/outlet ports at both ends are scientifically designed with arcs to ensure a reasonable angle for wire passage and avoid jamming. Some custom-made double-hole, multi-hole, and other special structures are available to adapt to complex processes such as multi-strand winding.

Machining Precision

Through multiple grinding processes (coarse, medium, fine, and ultra-fine), the surface roughness of the inner hole can reach Ra0.1, and is even lower at the curved ends (Ra0.025). The machining limits can achieve a hole diameter ≥0.15mm, wall thickness ≥0.10mm, and dimensional tolerances controlled within 0.01mm. Before leaving the factory, all parts undergo full inspection using an electron microscope to ensure a natural transition between the inner hole and the curvature, guaranteeing smooth wire passage.

Application Scenarios

Motor and Motor Manufacturing: Tungsten Carbide Guide Nozzle Parts are core components for winding stator and rotor coils in series-wound motors, fan motors, and micro motors. They guide the enameled wire precisely during winding, preventing scratches on the insulation layer and ensuring the conductivity and lifespan of the motor coils.

Wire Processing Industry: In the production of wires, cables, and stainless steel wires, they are used for guiding the wire during drawing and conveying processes. The smooth inner hole reduces surface wear, ensuring uniform wire diameter and a smooth surface.

Other precision machining fields: Compatible with CNC automatic winding machines and other equipment for various precision coil processing. It can also be applied to special processes such as multi-strand parallel winding of coils. Some customized models can even meet the guiding needs of wires with different specifications from 1 to 500mm.

Customization Services Supported

Standard specifications: A variety of standard models are available on the market, with complete parameters such as hole diameter, length, and outer diameter. For example, some models have hole diameters starting from 0.15mm, and the outer dimensions can cover a range of 1-500mm.

We support customization services: We support customization based on user-provided drawings or samples, including special hole diameters, irregular structures (such as flat or elliptical), and wire inlet/outlet ports with specific curvatures. Some manufacturers have low minimum order quantities and can also provide bulk customization and fast delivery services. The total supply can meet the purchase needs of more than 50,000 units at a time.
