Duubabka qaboojinta birta been abuurka ah waxaa ka mid ah duubo shaqo iyo duub duuban. Ujeedada ugu weyn ee duubista shaqada ee birta ah ee been abuurka ah waa in lagu rogo go'yaal bir ah habka duubista qabowga. Noocaan duudduuban wuxuu isticmaalaa qalab dhalaalid heersare ah (Furnace koronto koronto ah), qalabka sifaynta (electroslag remelting iyo sifaynta saqafka) iyo qalab been abuur ah (3150t hydraulic press) si ay u soo saaraan alloy bir been abuur ah banaan duudduuban oo tayo sare leh metallurgical. Marka la eego daawaynta kulaylka, tignoolajiyada kontoroolka kombayutarka ayaa la dabaqayaa Hubi in engegnaanta duubka iyo duub qoto dheeraanta lakabka adag ee jidhka ay leeyihiin soo saarid wanaagsan. Marka la eego habka daaweynta kulaylka, daaweynta kulaylka diyaarinta ah ee ku filan iyo deminta induction gaar ah (sii socota iyo mid ka mid ah), daaweynta cryogenic iyo xanaaqa ayaa loo isticmaalaa si loo helo lakabka shaqada ee adag iyo lebis. Moolka lakabka adag wuxuu gaari karaa in ka badan 30mm, oo leh caabbinta Wear ku filan, adkaanta iyo iska caabinta shilalka.
