Carbide Winding Alloy Nozzles
Introduction
SIPU tungsten carbide winding alloy guide nozzles and pins are ultra-precision wire guiding components engineered for high-speed automatic coil winding processes. Crafted from premium high-density tungsten carbide raw materials, these components deliver exceptional hardness, superior bending resistance, and outstanding wear durability, ensuring seamless integration with the long-term stable operation of automated mass-production winding lines.
Features
Premium Material: Made of high-density tungsten carbide, with a hardness exceeding HRC90, bending strength over 2300N/mm, and excellent structural stability.
Precision Machining: The inner bore and wire inlet/outlet arc ends adopt dedicated mirror grinding technology, with inner hole surface roughness of Ra0.1 and end arc roughness of Ra0.025, ensuring smooth wire transition.
Customizable Specifications: Supports ultra-fine wire processing (minimum inner hole diameter d1 ≥0.15mm), with full standard W-series specifications in stock; also provides customized sizes to meet special winding requirements.
Environmental Adaptability: Maintains stable dimensions and performance under high-temperature enamel wire melting conditions, with excellent corrosion resistance, suitable for humid, electroplating and other complex industrial environments.

Core Advantages
1. Superior Wear Resistance: Compared with ordinary steel nozzles, the wear resistance is 5-10 times higher, effectively avoiding enamel wire scratches caused by nozzle wear, and reducing maintenance and replacement costs.
2. Stable Precision Performance: The high-precision machining process ensures uniform tension during wire guiding, avoiding wire breakage and loose winding, and improving the qualified rate of finished coils.
3. High Compatibility & Convenience: Perfectly matches all SIPU automatic winding machines, with stable batch performance; standard specifications are in stock for immediate delivery, and customized products have short lead times.
4. Cost-Effective Operation: Long service life, low replacement frequency, reducing production downtime and overall operating costs, suitable for large-scale continuous production.
Application
Installed at the end of the manipulator of automatic winding machines, used for guiding enameled copper wire, ensuring stable wire feeding and winding.
Widely applied in relay coils, motor coils, semiconductor lead frames and other fields, directly determining the stability of winding quality and the service life of finished products.
FAQ
Q1: What gauge of enameled wire are your guide nozzles suitable for?
A1: It depends on customers' actual winding requirements. We provide fully customized nozzle sizes to match different wire diameters.
Q2: Do you have standard W-series guide nozzles in stock?
A2: Yes, mainstream W-series specifications are readily available for immediate shipment. We also accept custom orders for specific sizes and structures to meet unique winding processes.
Q3: How does the service life compare to ordinary steel nozzles?
A3: Our tungsten carbide nozzles offer a service life 5 to 10 times longer than traditional steel nozzles. This significantly reduces replacement frequency and minimizes production downtime.
Q4: Will your nozzles damage the insulation layer of enameled wire?
A4: No. We utilize a fine mirror polishing process for the inner hole and arc surfaces. This ensures an extremely smooth finish that fully protects the enamel varnish layer, preventing scratches or abrasion even during high-speed operation.
Q5: Are your guide nozzles compatible with SIPU automatic winding machines?
A5: Yes, absolutely. Our tungsten carbide guide pins and nozzles are perfectly compatible with all SIPU winding machine models, ensuring stable tension and consistent winding quality.
