Imishini yokugaya izinsimbi eziyigugu iyiyunithi lapho inqubo yokwakha insimbi iqhubeka khona. Phakathi nale nqubo izinto ezahlukene zensimbi zidlula ngemiqulu emibili, noma imishini yokuphatha izinto. Igama elithi “ukugoqa” lihlukaniswa ngokushisa lapho insimbi igoqwa khona. Imishini yokugaya izinsimbi zegolide isebenza ngokusebenzisa ama-roller amaningi ukulawula izakhiwo zomzimba zensimbi. Ekwenzeni amashidi egolide, inikeza ukujiya okufanayo kanye nokuvumelana kwensimbi yethusi yesiliva yegolide esetshenziswa ngayo. Imishini yegolide iqukethe ama-roller acindezela futhi acindezele insimbi njengoba idlula kuwo.

I-Hasung inikeza izinhlobo ezahlukene zemishini yokugaya insimbi, njengomshini wokugaya insimbi wegolide, umshini wokugaya insimbi kanye neshidi, umshini wokugaya kagesi kanye nemishini yokugaya ubucwebe njll. Ama-wire rolling mill angamayunithi lapho izintambo ezinkulu zidlula khona kuma-roller amabili anezikhala. Osayizi bezintambo bangenziwa ngokwezifiso ngokwezidingo. Imishini yokudweba izintambo enama-dies amaningi ngokunciphisa osayizi bezintambo ngamunye ngamunye ngesikhathi. Kusukela ku-wire ephezulu engu-8mm kuya ku-0.005mm noma ngisho encane.

Njengomunye wabakhiqizi bemishini yokugoqa abakhandi begolide abangochwepheshe, uHasung ube yingxenye ejulile emakethe yemishini yokugoqa, futhi uzibophezele ekuhlinzekeni amakhasimende ngemishini yokugoqa ubucwebe esezingeni eliphezulu, imishini yokugoqa igolide kanye neminye imikhiqizo nezinsizakalo.
