Two Decades of Precision Manufacturing Excellence
Dongying PUNI Industry & Trade Co., Ltd. (PUNI) was registered and founded in Dongying, Shandong Province in 2015. We have over ten years of deep engagement in precision casting and CNC metal precision machining. We integrate casting, machining, auxiliary surface treatment and export business, with independent qualifications for domestic sales of self-produced goods and import & export trade.
Our workshop integrates investment casting, resin sand casting, lost foam and centrifugal casting with full CNC finishing — turning, milling, boring, grinding and wire EDM — all under one roof.





We work to your drawings and samples, delivering high-precision non-standard parts with tight tolerances, minimal machining allowance and consistent batch quality.
