Pali mitundu ingapo yamakampani kapena opanga pamakina ogwirira zitseko:
Choyamba ndikutsanzira mapangidwe amakampani ena kapena opanga.Zogulitsa zamakampani kapena opanga zotere zilibe zopanga zatsopano komanso kuthekera kopanga zatsopano.
Chachiwiri ndi makampani kapena opanga omwe amapereka makamaka zogwirira zitseko za aluminiyamu, zogwirira ntchito zazitsulo zosapanga dzimbiri kapena zitseko zachitsulo.Zogulitsa zamtunduwu zimaganiziridwa makamaka ngati kuchuluka kwakukulu, kukhudzidwa ndi mtengo, ndipo sizifuna chitukuko chazinthu ndi zatsopano.
IISDOO, wopanga zinc aloyi chitseko amangoona ndi khomo hardware njira, osati ndi mphamvu chitukuko cha mankhwala kwa mitundu yosiyanasiyana ya makasitomala ndi zochitika khomo ntchito, komanso ndi malonda ndi Kukwezeleza mphamvu mu misika zosiyanasiyana.
Wachitatu ndi mtundu wotsogola waku Italy.Zogulitsa zawo zimapangidwa makamaka ndi mkuwa.Mtundu wawo uli ndi mbiri yapamwamba kwambiri padziko lonse lapansi.Komabe, zogulitsa zawo zitha kupezeka kwa makasitomala ochepa--- makasitomala apamwamba kwambiri.
