Технические характеристики
Bimetallic Extrusion Kinematics
The formation of bimetallic fins requires the rolling blades to act as both a forming tool and a bonding press. Nexmek blades are set at precise feeding angles that match the helix of the fin, ensuring that the aluminum flows into the desired profile without inducing excessive stress on the core tube.
- Multi-stage progressive diameter blade sets
- Calibrated for high-pressure helical formation
- Optimized for aluminum grades 1050, 1060, and 1100
Technical Compatibility & Performance
Our tooling is used to manufacture some of the industry's most durable heat exchange components.

Engineered for Aggressive Environments
Bimetallic tubes are the gold standard for Air-Cooled Heat Exchangers (ACHE) in oil refineries and petrochemical plants. Nexmek's rolling blades provide the precision necessary to ensure that the aluminum fins are robust enough to withstand high-pressure water cleaning and thermal cycling while protecting the structural core tube from corrosion.
