Shelefu imakhala yolimba ngati zopangira zimasankhidwa mosamala.Shelufu imatha kusonkhanitsidwa molunjika popanda zida monga kapangidwe ka mphodza.Kutalika kumatha kusinthidwa momasuka.Kulumikizana kwa matabwa ndi zowongoka kumapangitsa kuti alumali lonse likhale lolimba komanso lolimba.Gulu la alumali likhoza kusonkhanitsidwa mwachindunji.Mpira wapansi umawonjezeredwa pansi pa alumali yomwe ingateteze pansi ndikuwonjezera bata.Pambuyo asidi pickling ndi phosphorating mankhwala, kutentha electrostatic mphamvu kupopera mankhwala kumapangitsa pamwamba kaso ndi odana ndi dzimbiri.Shelufu imatha kuyika zinthu zamitundu yonse kuti igwiritse ntchito bwino malo.
1, Shelufu ndi yolimba popeza zopangira zimasankhidwa mosamala.
2, Shelufu imatha kusonkhanitsidwa mosavuta popanda kufunikira kwa zida chifukwa cha kapangidwe kake ngati sikwashi.Kutalika kumatha kusinthidwa momasuka.
3, Kulumikizana pakati pa matabwa ndi zokwera kumawonjezera kukhazikika komanso kulimba kwa alumali.
4, The alumali bolodi akhoza conveniently anasonkhana.
5, Padding ya mphira imayikidwa pansi pa alumali, kuteteza pansi ndi kupititsa patsogolo bata.
6, Kutsatira asidi pickling ndi phosphorating mankhwala, pamwamba ndi elegantly anamaliza ndi mkulu-kutentha electrostatic mphamvu kupopera mbewu mankhwalawa, kupereka onse kukopa zokongoletsa ndi kukana dzimbiri.
7, alumali ali ndi kuthekera kokhala ndi zinthu zosiyanasiyana, kukulitsa kugwiritsa ntchito malo.
8, Yoyenera makonda osiyanasiyana kuphatikiza malo ogulitsira, malo ogulitsa, zipinda zosungirako, magalaja, maphunziro, maofesi, maholo owonetsera, malo osungira, ndi zina zambiri.
