1. Real Challenges Faced by End Users
For production teams working in lithium battery material processing, screw elements in twin screw extruders are critical components that directly affect slurry uniformity, throughput stability, and maintenance frequency.
However, the harsh working environment — featuring abrasive powders, active solvents, and high mechanical stress — quickly wears down conventional materials like tool steel or standard PM alloys.
The result?
Frequent downtime, reduced mixing consistency, and rising maintenance costs.
End users are therefore increasingly searching for screw elements that can deliver both wear resistance and corrosion protection—without sacrificing toughness or precision.
2. Why End Users Choose TiCN Screw Elements
ZHITIAN’s TiCN (Titanium Carbonitride) screw elements are designed specifically to meet these challenges. By combining the hardness of TiC with the toughness of TiN, TiCN provides exceptional durability under continuous shear and chemical exposure.
For operators, this translates to longer production runs, consistent mixing quality, and reduced replacement frequency.
| End User Concern | TiCN Solution |
|---|
| Rapid Wear in Slurry Mixing | TiCN provides superior abrasion resistance in high-solid, high-shear operations. |
| Chemical Corrosion from Binders and Solvents | Excellent stability against NMP and lithium-based compounds. |
| Unexpected Downtime | Extended lifespan and stable operation reduce maintenance interruptions. |
| Performance Deviation Between Batches | Consistent dimensional accuracy ensures smooth engagement and stable torque transmission. |
3. TiCN Alloy: Designed for Real Production Conditions
TiCN screw elements are not laboratory prototypes—they are proven in industrial extrusion lines.
Through advanced powder metallurgy and strict process control, TiCN offers a balanced microstructure that performs reliably under both mechanical and chemical stress.
Key Advantages for End Users:
High Wear Resistance – Prevents premature erosion in abrasive electrode materials.
Corrosion Resistance – Maintains stability in chemically active slurries.
Impact Strength – Withstands sudden torque variations during start-up and shutdown.
Dimensional Precision – Ensures perfect fit with barrels and other elements.
Process Cleanliness – Minimizes contamination, improving slurry purity for energy materials.
4. Application Scenarios
TiCN screw elements are widely adopted by production teams in the battery materials, chemical, and polymer compounding sectors.
| Application Field | Typical Process |
|---|
| Lithium Battery Cathode/Anode Slurry | Continuous mixing and dispersion of active materials (NCM, LFP, graphite, SiC, carbon black) |
| Solid-State Battery Material Extrusion | Handling abrasive and thermally sensitive powders |
| High-Filler Compounds | Uniform mixing of powders, binders, and conductive agents |
| Conductive Paste or Adhesive Compounds | Ensuring high purity and fine dispersion |
For these applications, users report longer operational cycles, stable torque output, and fewer maintenance shutdowns—resulting in higher productivity and reduced total operating cost.
5. Quality Verification and Technical Support
From an end-user standpoint, reliability comes from traceable quality and consistent inspection.
Each TiCN screw element undergoes the following verification steps before shipment:
Material Analysis – Chemical composition and microstructure confirmation
Mechanical Property Testing – Hardness, impact resistance, and wear evaluation
CMM Dimensional Inspection – Tolerance precision within ±0.02 mm
Full Documentation – Including test certificates, inspection reports, and process traceability
Additionally, customized SOP (Standard Operation Procedure) and SIP (Standard Inspection Procedure) documents can be provided to match end users’ quality systems, ensuring traceability and compliance with global OEM standards.
6. End User Benefits Summary
| Key Performance Area | End User Advantage |
|---|
| Durability | Longer service life under high-load and high-abrasion conditions |
| Process Stability | Consistent mixing performance for better slurry quality |
| Maintenance Efficiency | Reduced replacement frequency and lower spare part cost |
| Operational Continuity | Less downtime, higher overall line efficiency |
| Material Purity | Reduced contamination for battery-grade applications |
7. FAQ: From End User Perspective
Q1: Can TiCN screw elements directly replace existing OEM parts?
Yes. They are designed with OEM-level tolerances and can be installed without any modification.
Q2: What benefits can production teams expect after switching to TiCN elements?
Users typically see extended operating time, more stable mixing, and improved consistency across production batches.
Q3: Does TiCN affect slurry purity?
No. TiCN’s surface is dense and inert, ensuring no contamination even under high shear conditions.
Q4: Can the screw element geometry be customized for different slurry formulations?
Yes. ZHITIAN provides customized designs based on flow patterns, shear levels, and process requirements.
Q5: Is technical support available for installation and performance optimization?
Yes. Our engineering team offers on-site and remote support for alignment, performance evaluation, and wear diagnostics.
