Fin ikanda kumurongo wanyuma hanyuma isahani yanyuma ikanda kumurongo wamashanyarazi nkuwiyitirira, mugihe yunamye, gukata, no kugoreka umuyoboro wa aluminium na Auto Al Tube Bending Machine na Skew no kuzinga Flattening Machine. Noneho umuyoboro winjizwamo kandi wagurwa na Double Station Shyiramo Tube na Expanding Machine kugirango uhuze umuyoboro na fin. Nyuma yibyo, isura irasudwa na Cooper Tube na Aluminium Butt Welding Machine hanyuma isahani yanyuma ikusanyirizwa hamwe na Machine yo guteranya Side Plate. Nyuma yo gutahurwa na Machine yipimisha Amazi, igice cyangiritse kumashini imesa hamwe na Blowing Device.
