Technology Spotlight
Advanced material treatments for superior durability and performance.
Why Nitriding is Essential for Screws and Barrels
The thermochemical treatment diffuses nitrogen into the surface of the steel, enhancing its hardness, wear resistance, and corrosion protection. This results in:
Enhanced Performance
- Increased surface hardness and wear resistance
- Low friction and improved polymer flow
- Improved fatigue strength and dimensional stability
Increased Longevity
- Enhanced corrosion resistance
- Compatibility with various materials
- Extended service life (cost efficiency)
| Feature | Nitroalloy 135M | 38CrMoAlA (Standard Nitriding Steel) |
| Surface Hardness (HRC) | 65-70 | 60-65 |
| Wear Resistance | Superior | Good |
| Corrosion Resistance | Excellent | Moderate |
| Temperature Resistance | High (stable at high temp.) | Moderate |
RK9999 - The Lightening Series
RK9999 is an extremely wear-resistant, dense, and crack-free tungsten carbide coating applied by the HVOF process. This versatile and popular choice is ideal for increasing screw life, especially when processing resins filled with abrasive additives. It typically wears at half the rate of other hard-faced or tool steel screws.
Key Benefits of RK9999 Coating:
- Porosity is less than 1%
- Corrosion resistance is 13 times higher
- Bond strength is 10,000 PSI (vs. 6000 PSI for standard TC coating)
- Flight wear resistance is 5 times higher
- Best-in-class adhesive wear resistance, highly compatible with Nitrided Barrels
- Full encapsulation option available for CPVC processing
Case Study: RK 9999 Coating in PVC Pipe Extrusion
Problem: A PVC pipe manufacturer experienced frequent screw wear and corrosion, resulting in downtime every 10-12 months.
Solution: Replaced regular screws with Nitroalloy 135M screws featuring the RK 9999 coating.
Results:
- Service life increased by 3x (to 3 years).
- Reduced maintenance by 45%.
- Improved output quality due to uniform melt flow.
ExtruMax
The Ultimate Wear-Resistant Coating for High-Filler Extrusion
Commercial pipe manufacturing comes with its own set of challenges – especially when dealing with high filler content. The ExtruMax Series is specifically engineered to tackle the pain point of early screw and barrel wear.
Why Choose ExtruMax?
