Technical Specifications
Precision Cold-Rolling Technology
The formation of aluminum fins requires a delicate balance of pressure and flow. Nexmek rolling blades are profile-ground using CNC precision to ensure that the extrusion process is smooth and consistent, preventing micro-fractures in the aluminum sleeve while maximizing the surface area for thermal exchange.
- Advanced profile geometry for uniform fin height on 1060 & 6063 alloys
- Low-friction design to prevent aluminum adhesion and galling under high pressure
- Engineered for high-volume industrial production compliant with ASTM A1012
Technical Compatibility & Standards
Our blades are compatible with all major industrial finning machines and can be customized for specific fin configurations.
