Graphite Bushing for Aluminum Extrusion Die
Product Overview
Jincheng graphite bushings for aluminum extrusion dies are precision-machined graphite inserts designed to guide and support aluminum billets through extrusion dies. These bushings provide excellent wear resistance and non-stick properties for smooth aluminum extrusion operations.
Our extrusion die bushings are manufactured from fine-grain isostatic graphite that withstands the high temperatures and pressures of aluminum extrusion. Custom inner and outer diameters are available to match different extrusion press models and die configurations.
Key Features
- High wear resistance for extended bushing life in aluminum extrusion
- Non-stick surface to prevent aluminum buildup on the bushing
- High temperature resistance up to 600°C aluminum extrusion temperatures
- Precision machined for accurate die alignment and billet guidance
- Good self-lubricating properties for smooth material flow
- Custom sizes available for various extrusion press models
- Easy to install and replace during die maintenance
- Cost-effective compared to carbide or steel alternatives

Frequently Asked Questions
Q1: How long do extrusion die bushings last?
A: Bushing life depends on extrusion pressure, temperature, and alloy type. Under typical aluminum extrusion conditions, graphite bushings last 50-200 tons of extruded material.
Q2: Can you manufacture bushings based on my die drawings?
A: Yes, we manufacture custom bushings based on your die drawings and specifications. Please provide your drawing or existing bushing dimensions for quotation.
Q3: Do you offer different graphite grades for different extrusion applications?
A: Yes, we offer various graphite grades from economical medium-grain to premium fine-grain isostatic graphite, depending on your performance and budget requirements.
Q4: How do graphite bushings compare to carbide bushings?
A: Graphite bushings are much more cost-effective and have better non-stick properties than carbide, but may need more frequent replacement in high-wear applications.
