High-Precision Copper Finned Tube Rolling Blade
Nexmek's High-Precision Copper Finned Tube Rolling Blades are engineered for manufacturers who demand excellence in heat exchanger production. These specialized tools are designed to mechanically displace the surface of copper tubes, creating integral fins with unmatched precision and surface quality.Manufactured from premium vacuum-hardened alloy steel, our rolling blades offer the perfect balance of toughness and wear resistance, ensuring consistent fin geometry over long production runs and minimizing downtime for tool changes.
Heavy-Duty High-Fin Copper Tube Rolling Blade
Nexmek's Heavy-Duty High-Fin Rolling Blades are specifically developed for the intensive cold-rolling processes required to produce high-profile integral fins on copper tubes. Unlike standard tooling, these blades are designed to handle the extreme material displacement necessary to reach fin heights of 10mm and above.Our advanced metallurgy ensures that each blade maintains its structural integrity and edge sharpness under the massive radial pressure of multi-stage finning operations, resulting in tubes with maximum surface area for high-performance air-cooled heat exchangers.
Ultra-High Density Micro-Fin Copper Tube Rolling Blade (50 FPI)
Nexmek's Ultra-High Density Micro-Fin Rolling Blades are the pinnacle of precision tooling for the HVAC-R industry. These blades are meticulously engineered to form up to 50 fins per inch (FPI) on high-quality copper tubing, providing the massive external surface area required for high-efficiency condensation and evaporation in compact units.Specifically designed for thin-walled copper, our micro-fin tooling utilizes advanced edge-geometry to ensure that every fin is formed with absolute uniformity, preventing tube collapse while maximizing the thermal performance of modern, eco-friendly refrigeration systems.
Precision Rolling Blades for Copper-Nickel (Cu-Ni) Finned Tubes
Nexmek's Precision Rolling Blades for Copper-Nickel (Cu-Ni) are engineered to meet the unique challenges of processing high-toughness, corrosion-resistant marine alloys. Cu-Ni 90/10 and 70/30 are significantly more abrasive and difficult to cold-form than pure copper, requiring specialized tooling with a high-strength matrix and anti-galling surface properties.Our Cu-Ni series blades feature a proprietary alloy composition that maintains edge integrity under the increased rolling torque required for marine heat exchanger production. This ensures that even the most demanding desalination and offshore cooling components are manufactured with precise fin geometry and zero surface defects.
Custom-Profile Enhanced Surface Copper Tube Rolling Blades
Nexmek's Custom-Profile Enhanced Surface Rolling Blades represent the cutting edge of thermal engineering tooling. As modern heat exchangers move toward ultra-high efficiency, standard helical fins are being replaced by complex 'Enhanced Surface' geometries such as T-shaped, Y-shaped, and cross-hatched profiles. Our specialized blade sets are designed to perform these intricate cold-forming operations with micron-level precision.By utilizing progressive rolling stages and proprietary edge-forming technology, Nexmek enables manufacturers to produce integral copper tubes with superior nucleate boiling and condensation characteristics, essential for the latest generation of high-efficiency centrifugal chillers and industrial heat pumps.
