Coating Service Overview

In wire and cable manufacturing, guide rollers and steel rings in wire drawing machines are exposed to continuous high-speed friction, resulting in severe wear over long-term operation.
To extend the service life of these critical components, tungsten carbide coating technology has become a widely used surface protection solution.
We specialize in tungsten carbide coating processing for large wire drawing steel rings, providing professional thermal spray coating services. With a typical coating thickness of 1.0–1.2 mm, our solutions improve wear resistance and help maintain stable production performance.
Tungsten Carbide Coating Material and Process
The coating uses tungsten carbide (WC) as the wear-resistant material.
Through advanced thermal spray technology, tungsten carbide powder is uniformly deposited onto the steel ring surface, forming a dense protective layer.
Tungsten carbide provides:
- Extremely high hardness
- Excellent wear resistance
- Strong friction resistance
The standard coating thickness:
1.0–1.2 mm
This thickness provides effective protection while maintaining component assembly accuracy.

Selection and Customization Guide
When selecting tungsten carbide coating solutions, consider:
Base Material
Steel rings are commonly made from steel substrates. Compatibility between substrate material and coating process should be evaluated.
Dimensional Accuracy
Since coating increases component dimensions, machining allowance should be considered before processing.
Working Conditions
The coating solution depends on:
- Wire material
- Line speed
- Wire tension
- Lubrication conditions
We provide customized coating services according to:
- Customer drawings
- Samples
- Equipment specifications
Providing detailed specifications helps us recommend the most suitable coating solution.
Maintenance Recommendations
To maximize coating performance:
- Regularly inspect coating surfaces for abnormal wear or peeling.
- Avoid strong impact during installation and operation.
- Clean surfaces with soft materials.
- Avoid corrosive cleaning agents.
Proper maintenance helps extend coating life and maintain stable equipment operation.
Frequently Asked Questions
1. Can tungsten carbide coating thickness be customized?
