Mai i tōna tīmatanga, kua piri Rongtai ki te ara o motuhake auaha hangarau me te R & D. He he rōpū o runga kakari-taranata hangarau i roto i te ahumahi, a ka kua whakapumautia he taiwhanga taumata-porowini, he pokapū hangarau hinonga taumata-porowini, he rangahau engineering taumata-terenga me te pokapū whanaketanga. E tohu ana i te taumata matatau o te hangarau arataki MF i te kāinga, me te ki waho, whai wāhi i roto i te whakahounga o te paerewa motu o "National Industrial Electric Heating Taputapu Waeine Technology", "Auautanga Waenga Coreless Induction ura" me "Momo Ngaohiko Auautanga faafariuraa Maha Auautanga Waenga Coreless Induction oumu Tautuhi Complete "Ko te whakatū o ngā paerewa kohi pūngao mō te maka ana oumu hiko.
