High-Efficiency Aluminum Finned Tube Rolling Blade
Nexmek's High-Efficiency Aluminum Finned Tube Rolling Blades are precision-engineered for the rigorous demands of industrial heat exchanger manufacturing. Designed for high-speed extruded and bimetallic finning operations, these blades ensure the consistent formation of high-profile fins with exceptional surface integrity.Our rolling blades are crafted from premium vacuum-hardened tool steels, specifically optimized to handle the unique flow characteristics of aluminum alloys such as 1060, 1100, and 6063. This specialized metallurgy reduces material adhesion and frictional heat, extending the life of the tool while maintaining sharp fin tips and precise root radii.

Heavy-Duty High-Fin Aluminum Tube Rolling Blade
Nexmek's Heavy-Duty High-Fin Aluminum Rolling Blades are engineered for the extreme material displacement required in the production of high-profile integral finned tubes. These specialized tools are designed to cold-roll aluminum surfaces into fins reaching heights of up to 15mm, providing an massive surface area expansion for high-performance cooling applications.Utilizing advanced progressive-profile geometry, our rolling blades ensure that the aluminum is extruded uniformly without compromising the integrity of the core tube wall. The cold-rolling process not only forms the fin but also work-hardens the material, resulting in robust, vibration-resistant cooling components that excel in demanding industrial environments.

Ultra-High Density Aluminum Micro-Fin Rolling Blade (50 FPI)
Nexmek's Ultra-High Density Aluminum Micro-Fin Rolling Blades represent the cutting edge of thermal management tooling. Specifically designed for the HVAC-R and automotive sectors, these blades are precision-ground to form up to 50 fins per inch (FPI) on aluminum tubing, maximizing heat dissipation capabilities in increasingly compact system designs.Engineered for high-speed cold-rolling machines, our micro-fin tooling features specialized edge geometry that reduces friction and prevents material adhesion. This allows for the consistent production of uniform, high-density fins on thin-walled aluminum alloys (1000 and 3000 series) without compromising the structural integrity or pressure-bearing capacity of the tube.

Rolling Blades for Bimetallic Aluminum Finned Tubes
Nexmek's Bimetallic Rolling Blades are specifically engineered for the extrusion process of composite finned tubes, where an aluminum sleeve is mechanically bonded and finned over a core tube of steel, stainless steel, or copper. These specialized tools are designed to handle the simultaneous requirements of high-pressure bonding and precision fin formation.Our bimetallic series features a progressive blade configuration that ensures the aluminum sleeve is extruded into helical fins with a mirror-like finish while maintaining a seamless, airtight seal over the core tube. This integral bonding eliminates contact thermal resistance and provides long-term atmospheric corrosion protection for the internal base tube.

Custom-Profile Enhanced Surface Aluminum Rolling Blades
Nexmek's Custom-Profile Enhanced Surface Aluminum Rolling Blades are at the forefront of advanced thermal engineering. Designed to meet the next generation of high-efficiency cooling requirements, these blades are capable of forming complex 'Enhanced Surface' geometries such as T-fins, Y-fins, and cross-hatched micro-structures directly from the aluminum tube wall.By precision-shaping the fin profile, our rolling blades create specialized micro-channels and spiral tunnels that significantly improve nucleate boiling and condensation efficiency. This specialized tooling is essential for manufacturing high-performance evaporators and condensers used in modern centrifugal chillers, industrial heat pumps, and power electronics cooling systems.
