Zhengna Technology (Zhejiang Zhengna Technology Co., Ltd.) is a China-based made-to-drawing manufacturer for custom metal and plastic OEM components. Since 1990, we have supported buyers that need stamping, CNC machining, injection molding, springs, fasteners, tooling, assembly, and inspection from one coordinated supplier. Headquartered in Yueqing, Wenzhou, Zhejiang Province, the company operates two production bases — in Zhejiang and Chongqing — with a combined facility area exceeding 20,000 square meters and > 400 employees.
The company holds four international quality certifications: IATF 16949:2016 (Automotive Quality Management), ISO 9001:2015, ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health and Safety). It is equipped with nearly 300 sets of metal forming, plastic processing, and mold manufacturing equipment, and produces over 100 million components annually.
Zhengna Technology's manufacturing capabilities span six core categories: custom metal stamping parts, CNC machining parts, sheet metal fabrication, precision springs, injection-molded plastic parts, and multi-component assembly. The company serves customers in the automotive, medical device, consumer electronics, and industrial machinery sectors across North America, Europe, and Asia.
Key differentiators include in-house mold design and tooling (with a lifetime mold guarantee), full-process quality control using CMM, X-ray spectrometry, salt spray testing, and optical projection equipment, and a quotation-to-delivery timeline of 7–15 days for standard orders.
30+ Years of Excellence in Precision Manufacturing & Engineering.
Stamping, CNC machining, injection molding, springs, fasteners, tooling, welding, assembly, and inspection are coordinated under one manufacturing system for made-to-drawing OEM parts.
Quality control covers material checks, first-article inspection, in-process measurement, CMM inspection, surface testing, packaging review, and batch traceability.
Our team reviews drawings, material selection, tolerances, surface finishes, tooling feasibility, and production risks before quotation to support smoother prototype-to-production transfer.
Zhengna Technology supports low-volume samples, pilot runs, and stable batch production for automotive, medical, electronics, industrial, robotics, and energy equipment projects.
A closer look at our production floors, office coordination, inspection areas, and manufacturing environment for custom metal and plastic OEM components.
To support growing demand for precision OEM components, Zhengna Technology expanded into a new 20,000 sqm manufacturing facility, strengthening stamping, CNC machining, injection molding, tooling, assembly, and inspection capacity.
In 2013, Zhengna Technology officially achieved the prestigious IATF 16949:2016 certification (Reg. No. 0478453), marking our entry into the elite tier of automotive-grade suppliers. Combined with our modernized facility, this rigorous quality management system ensures every component meets the zero-defect standards required by global industry leaders. We don’t just build parts; we build reliability.
Our journey began in 1990 with the establishment of our first specialized production plant. Founded on the principles of technical excellence and unwavering craftsmanship, this facility laid the cornerstone for what would become a 30-year legacy of manufacturing reliability and global partnership.
