I-Wuhan Ninestones Superatirans Coupd Couratirans Coupd ngo-2012 ngotyalo-mali ezi-2 zezigidi zeedola zaseMelika. Zinikezelwe ukubonelela ngesisombululo se-PDC. Siyayila kwaye sivelise bonke uluhlu lwe-polycrystalline yedayimane yedayimane (PDC), i-Dome PDC ye-oyile / yegesi, igesi yegesi, ubunjineli be-geologing, amashishini okutya kunye nemizi-mveliso yemigodi kunye nemizi-mveliso yolwakhiwo. Izimbini zendlela isebenza ngokusondeleyo nabathengi ukufumana ezona mveliso zineendleko zokufezekisa iimfuno zabo. Kunye ne-PDC yeMveliso yeMveliso, i-ninestones ibonelela ngemizobo eyenzelwe ngokwezifiso esekwe kwizicelo ezithile zokuqhuba.
Ilungu leTekhnoloji eliNgqogqa elaphuhlise i-Dome Pome PDC eTshayina. Ngomsebenzi ogqibeleleyo, ohambelana nomgangatho kunye nenkonzo ebalaseleyo, ngakumbi kwicandelo le-Dome PDC, i-ninestones ithathwa njengenye yeenkokeli zetekhnoloji.
AmaNinestones athobela ukuphuhlisa iimveliso ezigqwesileyo ze-PDC ngolawulo lwemgangathweni. Sidlulele kwizatifikethi: I-ISO1001 Umgangatho woLawulo lweNdalo, i-OO14001 yoLawulo lweNdalo kunye ne-OHSASA18001 eSebenzayo nezeMpilo.
