Izinzuzo Zethu

Isevisi esingayinikeza
1) Inkontileka esemthethweni ingasayinwa

2) Isivumelwano sokugcinwa kuyimfihlo singasayinwa
3) Isiqinisekiso sokubuyiselwa imali sezinsuku eziyisikhombisa
Okubaluleke nakakhulu: asikwazi ukunikeza umkhiqizo kuphela, kodwa isevisi yesixazululo sobuchwepheshe!
Ukupakisha Nokulethwa

Ukuqinisekisa kangcono ukuphepha kwezimpahla zakho, kuzohlinzekwa ngezinsizakalo zokupakisha ezinobuchwepheshe, ezinobungani nemvelo, ezilula nezisebenza kahle.
Iphrofayela Yenkampani

Isingeniso Senkampani

I-Shanghai Epoch Material Co., Ltd. itholakala esikhungweni sezomnotho—i-Shanghai.Sihlala sinamathela “Ezintweni Ezithuthukisiwe, impilo engcono” kanye nekomiti Lokucwaninga Nokuthuthukiswa Kobuchwepheshe, ukuze sisetshenziswe ekuphileni kwansuku zonke kwabantu ukuze senze ukuphila kwethu kube ngcono kakhulu.

Manje, sisebenzelana kakhulu nezinto ezingavamile zomhlaba, izinto ze-nano, izinto ze-OLED, nezinye izinto eziphambili.Lezi zinto ezithuthukisiwe zisetshenziswa kakhulu kumakhemikhali, imithi, i-biology, isibonisi se-OLED, ukukhanya kwe-OLED, ukuvikelwa kwemvelo, amandla amasha, njll.

Okwamanje, sinezimboni ezimbili zokukhiqiza esifundazweni saseShandong.Ihlanganisa indawo engamamitha-skwele angu-30,000, futhi inabasebenzi abangaphezu kuka-100, abantu abayi-10 kubo bangonjiniyela abakhulu.Sisungule umugqa wokukhiqiza ofanele ucwaningo, ukuhlolwa komshayeli, nokukhiqizwa ngobuningi, saphinde sasungula amalebhu amabili, nesikhungo esisodwa sokuhlola.Sihlola umkhiqizo ngamunye ngaphambi kokulethwa ukuze siqiniseke ukuthi sinikeza umkhiqizo omuhle kumakhasimende ethu.

Samukela amakhasimende avela emhlabeni wonke ukuthi avakashele imboni yethu futhi asungule ukubambisana okuhle ndawonye!

Kunesisho sakudala e-China esithi sijabule kakhulu ukubona abangani namakhasimende avela emhlabeni wonke!

Inkampani yethu idlule ohlelweni lokuphatha lwe-ISO 9001, futhi sinohlelo lwethu lwe-SOP lokukhiqiza, ukuthengisa, nangemva kwenkonzo yokuthengisa!Sethemba ukuthi singakunikeza isevisi enhle nephrofeshinali!
Umkhankaso Wokumaketha

Yamukela wonke amakhasimende avela emhlabeni wonke!
Sinamakhasimende emhlabeni wonke, futhi kuze kube manje, sisungule ukubambisana okuhle ne-sumsung, LG, LV, kanye namanye amakhasimende amaningi, futhi ukuze uthole ulwazi olwengeziwe, sicela usithinte!
