Introduction
In twin screw extrusion, the durability and consistency of screw elements determine both product quality and production efficiency. The TiCN (Titanium Carbonitride) screw elements are developed to address severe wear and corrosion challenges found in modern compounding, especially in lithium battery slurry mixing, high-filler plastics, and abrasive chemical extrusion applications.
TiCN combines the high hardness of titanium carbide with the toughness of titanium nitride, delivering a perfect balance of strength, toughness, and resistance under demanding conditions.
Advantages of TiCN Screw Elements
Designed for high-performance extrusion systems, TiCN screw elements provide a long-lasting and reliable solution that meets modern processing demands. Through powder metallurgy and precision CNC machining, every piece maintains structural uniformity, high bonding strength, and accurate geometry.
Key Benefits
- Extended Service Life: Provides superior wear life compared with conventional steels.
- Corrosion Resistance: Performs stably in lithium battery slurry, flame-retardant compounds, and high-filler plastics.
- Dimensional Accuracy: Maintains consistent torque transmission and shear precision over long production runs.
- Interchangeable Design: Suitable for a wide range of twin screw extruders used globally.
- Low Maintenance Costs: Reduced downtime and extended replacement intervals.
Sales Insight: Why TiCN Is a Game-Changer
Unlike coated elements that lose their protective layer over time, TiCN screw elements are made from solid high-performance alloy, ensuring uniform wear resistance throughout the material structure.
This design eliminates the risk of coating delamination and enables consistent performance under abrasive and corrosive processing conditions.
For users and equipment operators, this means longer uptime, better process stability, and lower operating costs.
Applications
TiCN screw elements are widely used in:
- Lithium battery electrode slurry compounding
- Engineering plastics with flame retardants
- High-filler compounding (CaCO₃, talc, SiO₂, etc.)
- Corrosive polymer extrusion
- Ceramic and pigment masterbatch production
Quality Control and Documentation
Each TiCN screw element is thoroughly inspected to ensure consistent quality and performance.
Testing includes:
- Material composition analysis
- Hardness and impact performance
- Dimensional verification via coordinate measuring machine (CMM)
- Assembly and compatibility checks
Comprehensive inspection reports, material certificates, and mechanical test data are provided for complete traceability and customer assurance.
