Iqela eliphambili lamanqindi lelo lokuqala lokuzibandakanya kuphando kunye nophuhliso lwemeyer Faka e China, ekhokela kwangaphambili.

E China, i-Wuhan Ninestones Core yeqela yayingowokuqala ukuphuhlisa i-PDC Dome, kunye netekhnoloji yalo kudala yagcina isikhundla sayo esikhokelayo emhlabeni. I-PDC Do Do Do Do Do Do Do Down iqulunqwe ngamaqhekeza amaninzi kunye neendawo zokutshintsha, ukubonelela ngokuchasene nefuthe lempembelelo ephezulu kwaye kufanelekile ukusetyenziswa komongo. Kuxelwe ukuba ubomi be-PDC Dome ngamazinyo ama-5 ukuya kweli-5 ukuba ngamazinyo e-carbide yemveli, okunciphisa kakhulu iindleko zokuqhuba nokuzisa utshintsho oluguqukayo kumzi mveliso wokuqhuba ioyile.

I-PDC Do Do Do Do Do Dome ayifanelekanga ukhuseleko oludanile kwaye lisothuke i-roller con con, i-Donhole Drill Bits, kwaye itsalele ingqalelo enkulu kwimakethi yamanye amazwe. Iqela le-PDC Doth Iimveliso ze-Wuhan Ninestones Prere Iqela laziwa kakhulu ngabasebenzisi basekhaya kunye nabangaphandle kwintsebenzo yabo ebalaseleyo, esemgangathweni, kunye ne-R & D egqwesileyo, kunye ne-R & D egqwesileyo.
