## Product Selection Notes

- A fin die forms, punches and lances metal fins used in heat exchangers such as condensers, evaporators, radiators and HVAC coils.
- Important fin die specification factors include fin material, fin thickness, fin pitch, tube pattern, hole shape, collar height, rows, die station layout and target strokes per minute.
- H type fin press lines are suited to stable high-volume fin production with matched decoiling, oiling, feeding, punching and stacking systems.
- C type fin press lines are suited to flexible factory layouts and customized heat exchanger fin production requirements.
- Vertical expanders are used after fin-and-tube assembly to expand tubes and lock contact between tubes and fins for heat transfer performance.
- Coil benders form heat exchanger coils after assembly and expansion, supporting HVAC and refrigeration coil shapes.
- Tube straightening and cutting machines prepare copper or aluminum tube from coil stock for heat exchanger production.
- Sinoak supports OEM and customized equipment projects for HVAC, refrigeration, cold storage, automotive radiator and industrial cooling manufacturers.
