Zhong Shen Industrial Co, Ltd

Zhong Shen Industrial Co., Ltd. has manufactured custom injection molded components for over 20 years from a single ~8,000 m facility in Jinhua, Zhejiang Province. We work as a general injection molding partner covering tooling design, molding, secondary operations (ultrasonic welding, pad/silk-screen printing, assembly), and export logistics out of Ningbo and Shanghai. Our press fleet spans 90 to 1,600 tons of clamping force, suited to general commercial and structural components. We serve OEM and ODM customers across consumer goods, hardware, outdoor products, electronics, and industrial equipment, and have shipped to 30+ countries. Quality is controlled at four stages: incoming material inspection, in-process sampling, first-article inspection, and final AQL-based outgoing QC, under an ISO 9001:2015 certified system. Every inquiry gets a response within one business day, and we offer a free DFM review before you commit to tooling.
