Pa May.2017, tidapereka 10kg platinamu-rhodium alloy high vacuum smelting zida ndi 100kg madzi atomization pulverizing zida ku kampani yamtengo wapatali yoyenga zitsulo ku North Korea.
Pa August.2021, tidapereka zida zoponyera golide za 2kg ndi chingwe chopangira ndalama kwa iwo.Pambuyo pake, tidapitilizabe kuwapatsa makina oponyera ndi vacuum granulators.
Nthawi zambiri zimadziwika kuti North Korea ili ndi mgwirizano wochepa ndi mayiko akunja.Hasung atalandira malamulo kuchokera kwa makasitomala aku North Korea, adadabwanso kuti makampani osungunula zitsulo ku North Korea adakula mwachangu.Panthawi yolankhulana ndi makasitomala aku North Korea, idamvetsetsa bwino zofunikira ndipo idafunikira zida za vacuum ingot.Ntchitoyi ndi yosavuta, kusindikiza kumakhala kolimba, ndipo kuchuluka kwa zida za granulation kumafunika kukhala oposa 90%.
Atatha kutsimikizira zomwe akufuna, Hasung adayankha mwachangu, ndipo adadutsa mobwerezabwereza kukonzanso ndikuyesa kuti atsimikizire mtundu wa chinthu chomwe chamalizidwa.Zida zinaperekedwa panthawi yake.Patangotha zaka zingapo pambuyo pobereka, kulephera kwa zida kunali kotsika kwambiri, kuchokera ku mayankho a kasitomala, ndizovuta zero, ndipo palibe mbiri yokonza.Njira yothetsera.
