HVAC Tube Manufacturing & Profiling

High-Efficiency Coiling and Bending for HVAC Systems

The HVAC and refrigeration industry moves on copper and aluminum. Manufacturing condenser coils, evaporator lines, heat exchangers, and distribution manifolds requires processing thousands of small-diameter, thin-walled tubes every shift without risking wall collapse or pinhole leaks.

Common HVAC Production Pain Points

· Tight Radius Coiling: Bending small-diameter copper tubes into tight 180-degree return bends often causes restrictions in coolant flow if the internal diameter collapses.

· High Leak Risks: Every weld joint is a potential leak point. Industry leaders aim to eliminate joints by bending continuous, long-length serpentine coils.

· Material Cost Management: Copper and aluminum prices are volatile; reducing scrap and optimizing wall thickness is critical to profitability.

The Wonsten Engineering Advantage

Specialized HVAC Serpentine Benders

Wonsten offers high-speed CNC bending configurations designed for continuous coil feeding.

· Mandrel-Free Options for Small Tubes: For ultra-fast cycling of small copper lines, our specialized tooling achieves tight bends without the slower cycle time of internal mandrels, maintaining high inner-flow volume.

· Multi-Groove Tooling: Run multiple small-diameter tubes simultaneously on a single machine cycle to double or triple your output per shift.

Extrusion Solutions for Heat Sinks and Manifolds

Our aluminum extrusion machines produce custom heat-sink profiles and heavy-walled headers with internal partitions, providing the foundation for high-performance commercial HVAC units.
