Chiyambi cha Kampani

Shanghai Epoch Material Co., Ltd. ili pakati pazachuma-Shanghai.Nthawi zonse timatsatira "Zida zapamwamba, moyo wabwino" ndi komiti ya Research and Development of technology, kuti igwiritsidwe ntchito pa moyo wa tsiku ndi tsiku wa anthu kuti moyo wathu ukhale wabwino.

Tsopano, timagwira makamaka ndi zida zapadziko lapansi, zida za nano, zida za OLED, ndi zida zina zapamwamba.Zida zapamwambazi zimagwiritsidwa ntchito kwambiri mu chemistry, mankhwala, biology, chiwonetsero cha OLED, kuwala kwa OLED, kuteteza chilengedwe, mphamvu zatsopano, ndi zina zotero.

Pakalipano, tili ndi mafakitale awiri opanga m'chigawo cha Shandong.Ili ndi malo a 30,000 square metres, ndipo ili ndi antchito oposa 100, omwe anthu 10 ndi mainjiniya akuluakulu.Takhazikitsa mzere wopanga woyenera kafukufuku, kuyesa woyendetsa, ndi kupanga misa, komanso kukhazikitsa ma lab awiri, ndi malo amodzi oyesera.Timayesa chinthu chilichonse chisanaperekedwe kuti tiwonetsetse kuti timapereka zinthu zabwino kwa makasitomala athu.

Timalandila makasitomala ochokera padziko lonse lapansi kudzayendera fakitale yathu ndikukhazikitsa mgwirizano wabwino limodzi!

Pali mwambi wakale ku China woti ndife okondwa kwambiri kuwona abwenzi ndi makasitomala ochokera padziko lonse lapansi!

Kampani yathu yadutsa mu kasamalidwe ka ISO 9001, ndipo tili ndi dongosolo lathu la SOP la kupanga, kugulitsa, komanso pambuyo pa ntchito yogulitsa!Tikukhulupirira titha kukupatsirani ntchito yabwino komanso yaukadaulo!
