Application Scenarios of Wire Winding Guide Pins

Wire winding guide pins are core auxiliary components of wire winding equipment, mainly functioning to accurately guide wires

such as enameled wires, copper wires, and yarns. They ensure that the wires complete winding according to the preset path,

tension, and angle, and are widely used in various scenarios requiring wire winding processing, as detailed below:

1)Manufacture of Motors and Transformers

This is the core application field of wire winding guide pins. In the winding process of stators, rotors, and transformer cores,

guide pins guide enameled wires through the core slots, ensuring neat wire arrangement and precise number of turns,

avoiding wire skipping and overlapping problems, which directly affect the energy efficiency of motors and the electrical

performance of transformers.

2)Production of Electronic Components

• Inductors: For winding of chip inductors and power inductors, guide pins need to adapt to the tiny winding shaft diameter, ensure the guiding accuracy of thin enameled wires, and prevent wire breakage or insulation layer wear.
• Relays and Solenoid Valves: The winding of electromagnetic coils for such components relies on guide pins to control the wire winding angle, ensure coil consistency, and improve the action sensitivity and stability of products.
• Sensor Coils: For the processing of coils in Hall sensors and electromagnetic induction sensors, guide pins need tomeet the high-precision and small-batch winding requirements.

3)Processing of Electrical Appliance and Home Appliance Accessories

It is used in the winding process of motors for home appliances such as washing machine motors, air conditioner compressor motors,

and electric fan motors. Meanwhile, it is also applicable to the production of accessories such as microwave oven high-voltage coils and rice cooker temperature control coils, ensuring the stable operation of home appliance products.

4)New Energy Field

• Power Batteries: In the busbar winding before welding of power battery tabs and the arrangement of internal lead wires of battery cells, guide pins are used to guide copper-aluminum busbars, ensuring connection reliability.
• New Energy Vehicle Motors: The stator winding of high-power vehicle motors requires large-caliber and high-wear-resistance guide pins to adapt to the high-speed winding of thick enameled wires.

5)Wire Processing and Textile Industry

In the stranding of wire and cable cores and the weaving of shielding layers, guide pins are used to sort multiple strands of wires to

avoid tangling and knotting.

In the textile industry, small guide pins are also used for yarn winding and thread path guidance of embroidery machines,

ensuring uniform yarn tension and improving the quality of fabrics or embroidery products.

6) Medical Devices and Precision Instruments

For the winding of ultra-precision components such as pacemaker coils and micro-induction coils of medical testing equipment,

guide pins made of ceramic or gemstone materials need to be adopted to reduce wire friction damage and meet the high reliability

requirements of medical products.

Problem Solving of Winding Nozzle

Reduction of scratches and pinholes on wire

Scratches and pinholes are serious problems for the wire being used.

Our winding nozzles reduce stress on the wire and solve such problems with a smooth, rounded shape and fine

hole final polishing.

Improved wear resistance

With conventional carbide nozzles, the wear on the tip of the nozzle progresses rapidly.

NHE joins single-crystal ruby and our company-made ceramic to the nozzle tip and the back end to produce a nozzle

with excellent wear resistance.
