Aluminum serpentine fin machines are used for making aluminum serpentine shaped fins. Its arbor size ranges from 4, 6, 10, 12 and 16 inches. It is 100psi moisture free. It cuts 40 fins per minute. Its machine speed is 200 per minute. Its maximum strip thickness is about 0.004 to 0.007 inch. Its strip width ranges up to 4.0 inch. Its power ranges from 110vac, 1 phase and 60 Hz. The patented pin roll tooling that produces high quality fins. The pin roll tooling pre-forms the fin bend radius to control radius location and size. Fin height adjustments are made to accommodate for different fins per inch. Its louver rolls cut with little friction and the louvers are air formed to achieve a consistent louver angle with little wear or damage to the rolls.
