Fin Mills

Fin Mills

World Leading Excellence for High Efficiency Fin Forming

World Leading Excellence for High Efficiency Fin Forming

Reliable Fin and Turbulator Forming Mills are the critical components supply source of a heat exchanger manufacturing operation.
COMCO FOS Series Fin Mills combine high precision and reliability in all manufacturing environments, from 24 hour high speed operation to special volume and prototype.

Excellence in Roll Forming Technology

Excellence in Roll Forming Technology

COMCO introduced the first Folded Aluminum Tube Mill for heat exchanger manufacturing in 1985.
Since then, for more than three decades, we have continued to innovate advances in folded tube roll forming technology to reduce material thickness, make complex shapes and integrate turbulator insertion in the roll forming process.
In-line flux application, inspection and automated collection are among other available features on COMCO Folded Tube Mills.
COMCO Roll Forming Mills are capable of producing a variety of complex configurations other than tubes and contribute to the production improvement by the roll forming.

Technologies for Microchannel Extrusion Tubes

Technologies for Microchannel Extrusion Tubes

COMCO COS Microchannel Cutting Lines bring the extruded aluminum microchannel tubing to the final precise dimensions required for brazed microchannel heat exchangers. COMCO COS Cutting Lines size precisely, remove camber, straighten and cut to length in a single in-line process.
COMCO's COS product line includes COS models for high speed-high volume and lower speed production processes.
Available optional items include automated collection and robotic packaging systems.

High Productivity and
Quality Stability Core Building

High Productivity and
Quality Stability Core Building

COMCO standard and custom configured Core Builders are available for all automotive and HVAC heat exchangers: radiators, A/C condensers and evaporators, heater cores, oil coolers, EGR coolers in fully automated and semi-auto machines and production line systems.

Wire Banding Machines

Wire Banding Machines

More Stable and Efficient Brazing with Wire Tying Process

More Stable and Efficient Brazing with Wire Tying Process

COMCO WOS Wire Banding Machines automatically wrap wires around heat exchangers prior to brazing to eliminate the need for braze frames.
This process improvement eliminates the costs of braze frames, braze frame maintenance, reduces the mass load in the brazing furnace and increases the furnace product capacity and simplifies the braze cycle development.
Moreover, it eliminates pre and post braze handling damage from heavy brazing frames.
COMCO WOS Wire Banding Machines automatically provide the consistent tension throughout assembled cores that is critical to braze quality.

Tank Crimping Machines

Tank Crimping Machines

High Productivity Crimping

High Productivity Crimping

COMCO Crimping Machines and Systems crimp-join radiator tanks and headers, condenser manifold sections, evaporator tanks and cores and other crimp-joined applications that require exact joining pressures for crimped joints.
COMCO Crimping technology is available in single station machines and high production multiple station lines integrated with leak checking, automatic station-to-station transfer and other custom engineered features.

EGR Assembly Lines

Innovative Automation Technologies

Innovative Automation Technologies

COMCO Finned Coil Hairpin Tube Insertion Machines automatically insert hairpin tubes with more than 1 meter length into fin stacks ready for expansion.
Back in the time when COMCO was developing this line, the insertion process was manually done by operators. Automatic tube insertion was a successful of COMCO and customer joint process technology innovation.
Automatic Insertion lines can include auto fin collection, hairpin alignment and hairpin expansion in continuous automated process lines.
