Tsopano zogulitsa zatumizidwa bwino kumayiko opitilira 30.

Bizinesi yokonza zojambula ndi zitsanzo ndi mwayi wa Makina a Haochang. Kampaniyo inakhazikitsidwa ndi Mayi Susen, mainjiniya wamkazi yemwe wamkulu wa yunivesite anali Mechanical Design and Manufacturing. Pambuyo pa zaka 4 zophunzira mwadongosolo, nthawi ina adagwira ntchito ngati katswiri pa malo mufakitale yayikulu yamakina kwa zaka 6, kenako adagwira ntchito ngati wogulitsa malonda akunja kumakampani ogulitsa kunja kwazaka zopitilira 20. Ndi zaka 30 akugwira ntchito m'makampani opanga makina, Mayi Susen adamanga maziko olimba a makina a Haochang Machinery.

Muyezo wamtundu wa Haochang Machinery womwe umakhazikitsidwa ndikufikira kapena kupitilira miyezo ya OE. Ndi chiphaso cha ISO9001-2015, Makina a Haochang ali ndi gulu lowunikira komanso kuyang'anira khalidwe lapamwamba kuti atsimikizire kuti malonda 100% akukumana ndi zofuna za makasitomala. Ogwira ntchito athu ali ndi udindo waukulu pamtundu uliwonse wa katundu. Chitsimikizo chaubwino cha chaka chimodzi mutakhazikitsa ndikudzipereka kwathu.

Makina a Haochang anathandiza bwino makasitomala kupanga malonda awo monga DIESSELTEK, SHAHYAR, TELFORD, DYNAGEAR, TRUST-DIESEL etc. Pakati pawo, mtundu wa DIESELTEK uli ndi gawo la 60% pamsika wamba. ndi ntchito zimatitengera ife kutumikira makasitomala bwino ndi bwino. Pazaka pafupifupi 30 zamakampani, Makina a Haochang adapeza zambiri pakutsata katsabola, kutumiza katundu ndi kukonza zinthu, kuti apititse patsogolo luso lathu.
