Graphite Nozzle for Metal Spraying
Product Overview
Jincheng graphite nozzles for metal spraying are precision-machined graphite components designed for wire arc spraying, flame spraying, and plasma spraying processes. These nozzles provide excellent wear resistance and non-stick properties for reliable metal coating application.
Our metal spraying nozzles are manufactured from fine-grain isostatic graphite that withstands the high temperatures and abrasive wear of molten metal spraying. Custom nozzle designs and sizes are available to match different spray gun models and coating requirements.
Key Features
- Excellent wear resistance against molten metal and abrasive particles
- Non-stick surface to prevent metal buildup on the nozzle interior
- High temperature resistance up to 800°C during metal spraying
- Precision machined bore for uniform metal particle stream and consistent coating
- Good thermal shock resistance for repeated spraying cycles
- Custom nozzle designs for various spray gun models and applications
- Easy to install and replace during routine spray gun maintenance
- Cost-effective compared to carbide or ceramic nozzle alternatives

Frequently Asked Questions
Q1: How long do metal spraying nozzles last?
A: Nozzle life depends on spray material, spray parameters, and nozzle material type. Under typical zinc and aluminum spraying conditions, graphite nozzles last 20-50 hours of spraying time before needing replacement.
Q2: Can you manufacture nozzles based on my spray gun model?
A: Yes, we manufacture custom nozzles based on your spray gun model or existing nozzle dimensions. Please provide your spray gun model or nozzle drawings for quotation.
Q3: How do graphite nozzles compare to carbide nozzles?
A: Graphite nozzles are much more cost-effective and have better non-stick properties than carbide nozzles, but may need more frequent replacement in high-wear applications.
Q4: Do you offer different nozzle designs for different spray materials?
A: Yes, we offer various nozzle designs optimized for different spray materials and coating requirements. Please specify your spray material and application for nozzle recommendation.
