Aia ʻo Shanghai Epoch Material Co., Ltd. ma ke kikowaena waiwai—Shanghai.Hoʻopili mau mākou i "Nā mea ʻoi aku ka maikaʻi, ola maikaʻi" a me ke komite i ka ʻimi noiʻi a me ka hoʻomohala ʻana o ka ʻenehana, e hoʻohana ai i ke ola o ke kanaka i kēlā me kēia lā e hoʻomaikaʻi i ko mākou ola.

I kēia manawa, pili nui mākou i nā mea ʻenehana honua, nā mea nano, nā mea OLED, a me nā mea holomua ʻē aʻe.Hoʻohana nui ʻia kēia mau mea kiʻekiʻe i ka kemika, lāʻau lapaʻau, biology, hōʻike OLED, kukui OLED, ka mālama ʻana i ke kaiapuni, ka ikehu hou, etc.

No kēia manawa, loaʻa iā mākou ʻelua hale hana ma Shandong Province.Uhi ia i kahi o 30,000 square meters, a he poʻe hana ma mua o 100 mau kānaka, a he 10 mau kānaka he poʻe loea.Ua hoʻokumu mākou i kahi laina hana kūpono no ka noiʻi, ka hoʻokolohua hoʻokele, a me ka hana nui, a hoʻokumu pū i ʻelua labs, a hoʻokahi kikowaena hoʻāʻo.Hoʻāʻo mākou i kēlā me kēia huahana ma mua o ka lawe ʻana e hōʻoia i ka hāʻawi ʻana i ka huahana maikaʻi i kā mākou mea kūʻai.

Hoʻokipa mākou i nā mea kūʻai mai ke ao holoʻokoʻa e kipa i kā mākou hale hana a hoʻokumu i kahi hui maikaʻi!

Loaʻa iā mākou nā mea kūʻai ma ka honua holoʻokoʻa, a hiki i kēia manawa, ua hoʻokumu i kahi hui maikaʻi me sumsung, LG, LV, a me nā mea kūʻai aku he nui pū kekahi, a no ka ʻike hou aku, e ʻoluʻolu e kelepona mai iā mākou!
FAQ
1) Hana ʻoe a kālepa paha?

He mea hana mākou, aia kā mākou hale hana ma Shandong, akā hiki iā mākou ke hāʻawi i kahi lawelawe kūʻai kūʻai hoʻokahi no ʻoe!
2) Nā huaʻōlelo uku: T / T (telex transfer), Western Union, MoneyGram, BTC (bitcoin), etc.3) Lead time≤25kg: i loko o ʻekolu mau lā hana ma hope o ka loaʻa ʻana o ka uku.＞25kg: hoʻokahi pule
4) SampleAvailable, hiki iā mākou ke hāʻawi i nā mea liʻiliʻi liʻiliʻi liʻiliʻi no ka loiloi maikaʻi! 5) Package1kg no kēlā me kēia ʻeke fpr samples,

25kg a i ʻole 50kg no ka pahu, a i ʻole e like me kāu e koi ai.6)StorageStore e paʻa paʻa i ka pahu ma kahi maloʻo, ʻoluʻolu a maikaʻi.
