Coating Service Overview

In wire and cable manufacturing, tower wheels are critical components that operate under high-speed rotation and continuous wire friction. Their surface performance directly affects production efficiency, equipment stability, and wire quality.
To extend the service life of medium wire drawing tower wheels, we provide professional tungsten carbide coating solutions. With a typical coating thickness of 1.0–1.2 mm, the coating provides excellent wear and corrosion resistance, making it suitable for various wire drawing and stranding equipment.
Tungsten Carbide Coating Process and Features
Tungsten carbide (WC) coating is widely recognized for its extremely high hardness and excellent wear resistance.
Through advanced thermal spray technology, tungsten carbide powder is heated and sprayed onto the tower wheel surface, forming a dense and durable protective layer.
Main Advantages
High Wear Resistance
The tungsten carbide coating effectively withstands:
- High-speed wire friction
- Abrasive wear
- Continuous mechanical stress
It significantly reduces wear and extends component service life.
Uniform Coating Thickness
Standard coating thickness:
1.0–1.2 mm
The thickness can be adjusted according to:
- Component size
- Operating conditions
- Wear requirements
Strong Bonding Strength
The coating provides excellent adhesion and is resistant to peeling under high-speed operation.
Smooth Surface Performance
A smooth coated surface helps:
- Reduce wire friction
- Minimize wire breakage
- Improve production stability
Applications

Frequently Asked Questions
1. Can tungsten carbide coating thickness be customized?
Yes. The standard thickness is 1.0–1.2 mm, but it can be adjusted according to component size and application requirements.
2. Does the coated tower wheel require additional machining?
Normally, the coated surface can meet standard operating requirements.
For applications requiring higher precision, light polishing or finishing can be performed.
3. Which tower wheels are suitable for tungsten carbide coating?
Suitable components include:
- Steel medium wire drawing tower wheels
- Guide rollers
- Wire passing wheels
Aluminum or other lightweight materials require evaluation before coating.
4. How long is the service life of coated tower wheels?
Service life depends on:
- Wire material
- Drawing speed
- Tension
- Lubrication conditions
Compared with uncoated wheels, tungsten carbide coated wheels can provide significantly longer wear resistance.
5. Do you provide refurbishment services for old parts?
Yes.
Worn tower wheels can be sent for inspection. If the substrate remains in good condition, recoating can restore performance and reduce replacement costs.
6. What is the delivery time for customized products?
Delivery depends on:
- Order quantity
- Component complexity
- Coating requirements
Small batch customized orders usually require approximately:
7–15 working days
