Duomei Shijia (Nanjing) Information Technology Co., Ltd.

DUOMEISHIJIA is an industry‑trade integrated manufacturer specializing in molecular hydrogen water generators and hydrogen‑rich water devices. Unlike pure trading companies that source finished goods externally, we combine in‑house R&D, manufacturing, full‑range quality inspection and dedicated B2B after‑sales service under one roof. With full‑stack industrial‑chain capabilities, we cater to global importers, wholesale distributors and brand owners, delivering steady OEM / ODM bulk supply and standardized export solutions. Every hydrogen water generator is completed within our own facility — from structural design, iteration of core hydrogen‑electrolysis technology, mold development, mass‑scale production and rigorous performance testing through to overseas after‑sales technical support. This end‑to‑house operation guarantees consistent product performance, stable hydrogen‑concentration output and reliable batch‑to‑batch quality for your large overseas orders.
